Microsoft: Outage on Outlook.com Caused By Firmware Issue

Microsoft has finally released some details on what caused that nearly 15 hour outage of Hotmail and Outlook.com on Tuesday; a problem with a firmware update at its data center, which it said caused a "rapid and substantial temperature spike" in its data center. Microsoft said that caused issues which prevented automatic failover of its services and prevented access to mailboxes housed on the servers in that data center, and also needed "human intervention" that required significant time to bring the service back to life.
