Is CloudAMQP down?

We've received various alert notifying us about couple of servers deployed on Azure West US not being reachable. Apparently this seems to be related specific to this region impacting 25% of the servers.

Microsoft Azure confirmed they were having network issues on West US region. For now, most of the servers are operational. We'll keep monitoring for the following hours.

**Summary** Between June 25 and June 26, our monitoring system incorrectly reported some dedicated servers as unreachable and sent "server down" notifications for servers that were in fact operating normally. This was a monitoring-side issue only — no customer servers or services were actually down, and no data or message delivery was affected. **Impact** Affected customers received one or more alerts indicating their dedicated server was down. These alerts were false positives. The servers themselves remained healthy and fully available throughout the incident. **Root cause** Before connecting to a server, our monitoring system performs a network authorization step. A defect in how one component handled a transient network hiccup could leave a monitoring process unable to complete that step, after which it failed to connect to the servers it was responsible for checking. The servers themselves stayed healthy and available throughout — the monitoring process had simply lost its ability to reach them, and reported them as down. **Resolution** We identified the affected monitoring processes, confirmed the root cause in production, and deployed a fix that makes this authorization step resilient to such transient failures and able to recover automatically. After deploying, we monitored the system to confirm that notifications returned to normal. We apologize for the confusion these false notifications may have caused.

Between 17:30 and 20:00 UTC on 2026-05-30, our server monitoring system generated a large number of false "server_unreachable" alerts. Clusters were operational and healthy throughout this period — no customer data or message delivery was affected. The alerts were caused by a rolling restart of our monitoring service, during which individual monitoring workers went offline mid-cycle and lost state. This caused the workers to report connection timeouts for servers they could no longer reach — even though those servers were fully healthy. We apologize for any concern this may have caused.

We are investigating connectivity issues affecting some CloudAMQP instances in Azure West Europe. Affected instances may see connection failures or unexpected restarts. The root cause is an ongoing Microsoft Azure platform incident in the West Europe region (started 14:31 UTC, 23 May 2026). Microsoft is investigating.

Resolved — Microsoft has confirmed that the Azure West Europe Virtual Machines incident is resolved. The impact window was 14:09–14:13 UTC on 23 May 2026, during which a limited number of customers may have experienced connection failures or unexpected Virtual Machine restarts. The Azure environment self-healed and the service has been confirmed restored. Affected CloudAMQP instances should now be operating normally.

Since around 8pm UTC last night, some metrics are not being forwarded to legacy integration. Prometheus integrations not affected. We are investingating.

A fix has been implemented and we are monitoring the results.

# Legacy host metrics integrations degraded Incident window: 2026-05-21 18:37 UTC – 2026-05-22 04:05 UTC \(9h 28m\) Affected service: Legacy metric integrations \(CloudWatch, Datadog, Librato, New Relic, Splunk, Stackdriver\). Host metrics affected, not broker metrics, nor was internal monitoring or console graphs. ## Summary For ~9.5 hours, the service that collects host-level metrics \(CPU, memory, disk, network\) for legacy third-party integrations entered a crash loop and stopped shipping data. ## Root Cause An internal credential-signing service was migrated to a new container runtime the afternoon before. Due to a bug with environment variables the collector could not renew it's credentials. The collector's existing credential remained valid for several hours, so the failure only surfaced when it tried to renew. ## Resolution On-call staff detected the failure early morning, developers helped restore the service and collector recovered at 04:05 UTC. ## Prevention * All services, both signing and collector report failed authentication attempts earlier and with higher severity * Metrics pipeline alarm thresholds was tightened so a similar drop in data triggers alarms faster.
