Yesterday, packages.microsoft.com—the repository from which Microsoft serves software program installers for Linux distributions together with CentOS, Debian, Fedora, OpenSUSE, and extra—went down arduous, and it stayed down for round 18 hours. The outage impacted customers attempting to put in .NET Core, Microsoft Groups, Microsoft SQL Server for Linux (sure, that is a factor) and extra—in addition to Azure‘s personal devops pipelines.

The outage is considerably better-documented at this .NET Core subject report on Github, with many customers from all all over the world sharing their experiences and theories.

The brief model is that all the repository cluster that serves all Linux packages for Microsoft was utterly down—issuing a variety of HTTP 404 (content material not discovered) and 500 (Inside Server Error) messages for any URL—for roughly 18 hours. Microsoft engineer Rahul Bhandari confirmed the outage roughly 5 hours after it was initially reported, with a cryptic remark in regards to the infrastructure crew “operating into some house points.”

Eighteen hours after the problem was detailed, Bhandari mentioned that the mirrors have been as soon as once more out there—though with quickly degraded efficiency, possible as a result of chilly caches.

We’re nonetheless ready for a complete incident report, since Bhandari’s standing updates present clues however no actual explanations. The excellent news: We are able to affirm that packages.microsoft.com is certainly up as soon as once more, and it’s serving packages because it ought to.
