Alaska Airlines has said that the global Azure outage disrupted systems used by Alaska and Hawaiian Airlines, affecting websites and other services.
Microsoft’s global outage affected customers and Microsoft services using Azure Front Door between 15:45 UTC on Oct. 29 and 00:05 UTC on Oct. 30, causing latency, timeouts and errors, according to its Azure status page.
The company listed impacts across services including Azure Portal, Azure SQL Database, Azure Communication Services, Media Services, Microsoft Entra ID, Microsoft Sentinel and others.
Microsoft said the incident stemmed from an inadvertent tenant configuration change in Azure Front Door that propagated a faulty state across edge nodes. Engineers blocked new customer configuration changes at 17:30 UTC and began deploying a “last known good” configuration at 17:40 UTC, followed by a global push at 18:30 UTC.
By 00:05 UTC on Oct. 30, Microsoft said impact was mitigated. It added that while error rates returned to pre-incident levels, a small number of customers could still see residual issues, and customer configuration changes remained temporarily blocked during mitigation. A post-incident review will be shared with impacted customers within 14 days, the company said.
