If you've had or are having problems using websites and apps today, it might well be due to the Microsoft Azure outage.

While the IT breakdown isn't nearly as bad as the CrowdStrike boot-loop crisis from earlier this month, not that that was exactly Microsoft's fault, various big names are experiencing or have experienced connectivity problems as a result of Azure's network infrastructure multi-hour meltdown.

Customers may have experienced issues connecting to Microsoft services globally

The Windows giant said the issue lies with its network infrastructure, its Azure Content Delivery Network (CDN), and related CDN-like Azure Front Door service, which all together means "customers may have experienced issues connecting to Microsoft services globally."

It started to fall apart at about 1145 UTC today, the day Redmond is due to report its latest quarterly financial results.

"An unexpected usage spike resulted in Azure Front Door (AFD) and Azure Content Delivery Network (CDN) components performing below acceptable thresholds, leading to intermittent errors, timeout, and latency spikes," Microsoft noted at 1900 UTC.

"We have implemented network configuration changes and have performed failovers to provide alternate network paths for relief. Our monitoring telemetry shows improvement in service availability from approximately 1410 UTC onward."

Interestingly, while the service is being fixed, the cure may cause a little more disruption. Microsoft explained:

So in about an hour's time, from publication, Redmond reckons all should be well again. Let's take a look at the impact of Azure's instability so far.

Unsurprisingly, Minecraft maker Mojang, a subsidiary of Microsoft, said users may "may experience some intermittent failures connecting to our services due to issues with Azure." While Minecraft has both single and multiplayer modes, it does require users to authenticate their account before downloading and playing the game, and if these remote authentication services fail due to Azure being wobbly, then no more playtime.

Incidentally, your humble vulture tried to see what would happen if he attempted to install the Windows version of Minecraft on his PC, and discovered the launcher would spit out an error message, and the Java version wouldn't launch, likely because the Microsoft Store is also facing downtime amid the Azure breakdown. So that's fun.

Microsoft 365 is another Redmond-operated service confirmed to be impacted, and although there have been some murmurings about MSFT's Xbox Live going down, too, so far the official Xbox status page says everything is fine. Let us know in the comments section if that matches your experience.

Game creation engine Unity additionally reported problems with Azure that is preventing downloads and uploads. MongoDB and Moesif also said the Azure outage caused them headaches, respectively for their Cloud and web portal services.

"This is causing degraded health of some Atlas Clusters globally," MongoDB wrote. "In some cases, the cluster may not be accessible."

Microsoft-owned GitHub said its Codespaces tool had issues around 0930 EST, and about half an hour later DocuSign noticed problems with its Rooms feature. Both diagnosed the problem as having originated from an outage at third-party, which we assume is Azure, tho it's not confirmed.

GitHub and DocuSign claimed the issue was fixed around the same time, which may imply Microsoft is indeed making progress on bringing Azure back up.

Starbucks also reportedly experienced an outage with its mobile app, though the latte-slinging corporation hasn't responded to The Register's inquiries about whether this is related to Azure. We suspect it might not be a coincidence since complaints about problems with Starbucks on Downdetector are very similar in pattern to gripes about Microsoft 365. ®
