Is cdnjs Down Right Now? Check if there is a current outage ongoing.

We're investigating an outage with the cdnjs API. We believe this to be caused by an upstream provider issue.

At this time we believe the fix to restore file content and SRI hashes is working as expected.

A backfill has been completed that is believed to have restored files to their previous states, with the SRI hashes reverted to what they were prior to this incident. We'll continue to monitor for reports of any hash mismatches, which should be reported in the issue on GitHub at https://github.com/cdnjs/cdnjs/issues/14210

We are aware of an issue impacting multiple libraries where SRI hashes have changed. We have found the cause of the change to the file contents/hashes and are actively working to restore the previous contents/hashes. No files on the CDN have been compromised, the contents/hashes have changed due to libraries being reprocessed with different minification logic. We are tracking this on GitHub in https://github.com/cdnjs/cdnjs/issues/14210

This incident has been resolved.

At this time the API is now returning valid responses for all requests. We will continue to monitor the situation to ensure this remains true.

We are continuing to investigate the 502 issue with the API. It appears to be impacting a limited subset of requests at this time.

We are aware that the cdnjs API is returning 502 responses for many requests. We are investigating this issue. (Edit: This incident has been back-dated to the believed initial starting point of impact for requests. Incident was initially declared at 11:30 UTC.)

The API service has now been restored.

We are confident that a fix is now in place for the intermittent issues previously experienced by some users with the API service. We will continue to monitor the situation to ensure this remains the case.

Our team are online and have temporarily restored the API service. We continue to investigate the root cause and look for a solution.

We are aware that some requests to the API may receive invalid responses. We are looking into this.

We are confident that the API service and the website are both stable.

A further fix has been implemented and the API service appears to be healthy now. We will continue to monitor this.

We are aware of a secondary issue where some requests are receiving a 530/1016 Origin DNS error and we are working to resolve this.

We have implemented a fix for the 502 issues -- the API service, as well as the website, appears to be operational once again. We will continue to monitor the situation to ensure this remains the case.

We continue to investigate the 502 error issue with the API and are aware that this may also be impacting accessing library information on the cdnjs website as this is backed by the cdnjs API service.

We are aware that the cdnjs API is currently returning a 502 Bad Gateway error for requests. We are investigating this and will update once we know more.

This incident has been resolved.

The API is now responding nominally. We will continue to monitor the situation to ensure the cdnjs API remains stable.

We are aware that the cdnjs API is currently returning an Argo Tunnel error. We are investigating this and will provide an update as soon as we know more.

At this time we are confident that access to the CDN has been restored for all users of cdnjs.

A fix has been implemented that should allow users in mainland China to access cdnjs. Cloudflare will continue to monitor the situation.

Cloudflare has now implemented a fix for the CDN and SSL errors should begin to resolve. Users in mainland China may still see issues connecting to cdnjs and we continue to work to resolve this.

The team at Cloudflare are aware of the issue and are working to fix it. You can track their updates at https://www.cloudflarestatus.com/incidents/vtlmfzqmc8h7 -- we will continue to share updates here as well.

We are aware that requests to cdnjs.cloudflare.com are currently returning a bad SSL response. We are working to establish the root cause and get a fix implemented.

We are confident at this time that we have resolved the errors seen with the website & API, both are now handling library requests correctly.

The cdnjs website and API are now both using updated packages metadata, allowing them to correctly respond to requests for libraries without error. We will continue to monitor both the API and website to ensure this doesn't happen again.

The cdnjs API is now correctly responding to library requests, however, we are still working to resolve the issue present on the website.

We have identified the source of the failure, the metadata used for the website and API for packages data was unable to generate correctly, resulting in the data used being corrupted. We are working to mitigate this and regenerate the data.

We are aware of reports that some libraries on the cdnjs website and API are resulting in an error response. We have notified our team and are looking into the root cause of this issue.

We are confident at this time that all cdnjs assets are now available on the CDN once again. Cloudflare is continuing to see good recovery on their incident as well: https://cfl.re/2VbxQ96

It would appear the origins for cdnjs.cloudflare.com are now available again and requests to uncached cdnjs assets should now work as expected. We will continue to monitor for a while to ensure this is stable. For more information on the larger Cloudflare outage, please follow their status page updates: https://cfl.re/2VbxQ96

We believe this is due to the ongoing incident Cloudflare has: https://cfl.re/2VbxQ96 - Requests to cached assets should work but any request for an asset not cached on cdnjs is likely to fail at present.

We are aware of an issue affecting requests for certain assets resulting in a 522 or 523 response. We are currently investigating the source of this issue.

We are now confident the fix is working as expected. The cdnjs website and API are now showing libraries and their versions correctly.

We have now implemented a fix and believe that packages should now be showing correctly on the cdnjs website and via the API. We will continue to monitor this whilst the caches clear to ensure this issue is no longer present.

We have identified the issue as a fault within our package generation script that feeds cdnjs repository information to our website & API. We are tracking this issue on GitHub: https://github.com/cdnjs/cdnjs/issues/13654

We have been made aware of an issue with the cdnjs website that means certain library pages are not showing, with an error message "version not found!" shown instead. Further, it appears that on the same libraries, their API responses do not contain the correct versions. This does not affect the libraries available on the CDN, cdnjs.cloudflare.com.

Cloudflare is confident at this time that services have been restored to normal and users should no longer be affected by this outage. At this time we will, therefore, mark the incident as resolved. If you are still seeing any issues with the cdnjs services, please let us know through Twitter and we can look into it further.

Cloudflare is stating that they have implemented a fix for this issue, we will continue to monitor our own user reports of any further outages and also monitor the Cloudflare incident.

Cloudflare have now raised an incident on their status page due to the outage: https://www.cloudflarestatus.com/incidents/tx4pgxs6zxdr

We are aware of reports from users that cdnjs (website & CDN) is returning 502 Bad Gateway errors. We believe this is a larger issue with Cloudflare itself as many other websites behind them are also down. We will keep this updated as we know more.

Cloudflare have confirmed this issue is now resolved and all cdnjs services should be accessible again.

Cloudflare and the responsible network for the route leak have now fixed the issue. Connectivity should now be recovering. We will continue to monitor the effects on the cdnjs services and follow updates from Cloudflare.

Cloudflare are still working to resolve the route leak that is causing major outages across the internet. Follow their status updates at https://www.cloudflarestatus.com/incidents/46z55mdhg0t5

Cloudflare have identified the network issue as a route leak and have their network operations team engaged in restoring services. Keep updated via their incident at https://www.cloudflarestatus.com/incidents/46z55mdhg0t5

We have been made aware of some users who are having connectivity issues to both our main website and the CDN service. We believe at this time that this is due to network issues that Cloudflare are experiencing. This is likely to also impact our API, though we have no reports of this yet. You can track the Cloudflare incident at https://www.cloudflarestatus.com/incidents/46z55mdhg0t5

Cloudflare have purged all affected resources from the cache and are confident that this issue has now been resolved.

Cloudflare have released a fix for the issue. Please let us know via Twitter or our main GitHub repository if you continue to see issues. Twitter: https://twitter.com/cdnjs or https://twitter.com/cdnjsStatus GitHub: https://github.com/cdnjs/cdnjs/issues/13324

Cloudflare have identified the source of the issue and are currently working to roll out a fix to the missing CORS headers.

We have been made aware of some responses lacking CORS headers from the CDN service. We are working with Cloudflare, who have recently deployed changes, to resolve this.

We and Cloudflare are happy to say that the CDN is now performing normally.

We believe that the CDN is now serving all requests with valid responses. We sincerely apologise for the long delay in resolving this issue. We will continue to monitor the situation for a while longer to confirm all is okay.

Cloudflare have now identified the failing origin servers and they have been removed from the load balancer. CDN responses should now return to normal and cdnjs/Cloudflare will continue to monitor this.

To assist Cloudflare in identifying bad origin servers for the CDN, please post any failed requests on our GitHub mega-issue with full request and response headers along with the resource URL that failed: https://github.com/cdnjs/cdnjs/issues/13165

Cloudflare are now handling this issue and actively looking to resolve it as it is a failure of their infrastructure behind cdnjs that is causing this issue. They apologise for any delay due to engineering staff being away on holiday leave.

We are aware that a higher percentage of requests are beginning to fail now. We apologise for the delay in resolving this. Please continue to post full request/response headers on the GitHub mega-issue to assist Cloudflare in resolving this: https://github.com/cdnjs/cdnjs/issues/13165

We believe we have identified the issue relating to the minority of requests that are receiving a bad response. We have alerted Cloudflare to this and are currently awaiting their response to resolve this.

To help us with investigating this issue we have created a GitHub mega-issue. Please post any failed requests will full request/response headers and the resource URL that failed: https://github.com/cdnjs/cdnjs/issues/13165

We have been made aware that our CDN is in a small number of requests giving an invalid response that is a 404 with missing CORS headers. We are currently investigating this and will post an update here shortly.

We believe that the CDN is now back to normal and service should be fully restored to cdnjs! Apologies from all of us here at cdnjs for the delay in getting this resolved and for the drop in service. Have a great weekend making use of cdnjs in all your projects!

This issue had resurfaced due to an automatic process with Cloudflare reinstating a broken node into the load balancer. This has now been stopped and we will continue to monitor to ensure the CDN is performing normally.

Further reports have been made of continued issues with the CDN and these have been passed on to Cloudflare to ensure that the issue is resolved in a timely manner. We apologise for the drop in service to those affected.

Cloudflare have identified the issue a recurrence of the CDN failure we experienced in December. They have now fixed the issue and we are monitoring the CDN to ensure service is restored.

To assist in the diagnosis of the issue, please post any failed requests with full request/response headers on our GitHub mega-issue: https://github.com/cdnjs/cdnjs/issues/13165

It appears that the CDN is failing to serve a small minority of requests again. We have alerted Cloudflare and are waiting for their response.
