   The service degradation affecting some EMQX Cloud deployments in the Azure West US 2 region has been resolved. According to Azure’s latest update, the underlying Azure service disruption occurred between 04:24 UTC and 20:18 UTC on 29 May 2026 and was caused by severe weather in the region, including lightning strikes, which resulted in utility power loss and related cooling issues across multiple datacenter buildings.
