The Time it Wasn't DNS
Abstract
In January of 2023, the Microsoft Azure Wide Area Network experienced a global outage. If you were a Microsoft customer at the time, you were impacted by this outage. Sean walks us through the numerous factors - events and conditions - that contributed to the outage and explains why it's not always DNS. (Spoiler: sometimes it's BGP)
