- Microsoft fiber foul-up cut off Azure California for almost five hours
Microsoft's routine network maintenance on July 23rd caused a five-hour outage for Azure users in its West US region due to a bug in the request conversion system, which incorrectly removed IP routes. The issue was resolved by 19:41 UTC after rolling back changes, impacting traffic between datacenters and the wide-area network.
