emnify Status

## Summary Due to a full outage of emnify’s LTE signalling carrier for the 90143XXX and 29509XXX IMSIs, customers were unable to attach to LTE networks during the impact duration of 29min. Due to static routing in 3GPP signalling systems, there is no failover to alternate carriers. Most devices were able to connect to alternative RAT types \(2G/3G\) or using alternate IMSIs. Existing data connections were not impacted. ## Timeline \(UTC\) | Time | Event | | --- | --- | | 07:47 | **>>>INCIDENT STARTS HERE<<<** Carrier applies configuration change to their Diameter Routing Agents, which triggers a software bug. LTE signalling links between emnify and carrier are all shut down. | | 07:52 | Automated alert raised | | 08:04 | Internal incident created | | 08:16 | LTE signalling links up again **>>>INCIDENT STOPS HERE<<<** |
