Cambium Networks Outage History

Outage for some EU west pods (5,9,16,22,24) At around 11:43 UTC on Sunday 12 July 2026, some cnMaestro services in the EU west region began to fail due to an EC2 failure. Compounding this, automated recovery of the EC2 workloads also unavailable. AWS support are looking in to the root cause, and we will update this notice if more information becomes available. No network outages were recorded, but configuration changes and metrics collection will have failed for customers on impacted pods. Alternative recovery was completed by 01:58 UTC on Monday 13 July 2026\. We apologise for any inconvenience..

Workarounds have been put in place, and the region is fully operational.
