Brief Hybrid Agent Disruption on 2026-08-29
Last updatepostmortemAug 31 · 18:15 UTC
**What happened** During a planned network migration on 2026-08-29 17:35 UTC, we disconnected existing PrivateLink consumer VPC endpoints as part of the cutover. Hybrid customer agents connecting via PrivateLink lost their connections and were not able to reconnect until the new endpoints were provisioned. Full recovery at 18:05 UTC, ~30 min. **What went well** * No data loss; agents automatically re-attached with no customer action required. **What could have gone better** * Provisioning new endpoints took longer than expected. * We did not proactively communicate to affected customers ahead of the maintenance window. **Follow-ups** * We will update our standard procedures for planned maintenance to ensure communication of operations that may cause delays in customer pipelines.
