outlook Microsoft blames overheating for Hotmail and Outlook outage

Microsoft has blamed overheating at one of its datacentres for Tuesday's outage of Hotmail and Outlook.com, promising it is implementing changes to prevent this happening again.

Microsoft has blamed overheating at one of its datacentres for Tuesday's outage of Hotmail and Outlook.com, promising it is implementing changes to prevent this happening again.

 
The software giant said that on 12 March at 3:35pm PDT its service was disrupted by a spike in temperature at part of one of its datacentres. The jump in heat occurred during regular firmware updates, but failed to work properly this time in an “unexpected way.”
 
The company said its safeguards immediately came into action, restricting the outage to just that part of the infrastructure, which affected Hotmail, Outlook.com and SkyDrive.

Microsoft said it required both software fixes and “human intervention” to fix the problem, stating that the latter is usually not required for outages, making it a more time-consuming task to bring everything back online. Full services were restore by 5:43am PDT on 13 March.
 
Hotmail, a once dominant email service, now lives in the shadow of rival email facilities like Gmail, making any disruption to availability a potential instigator of mass migration to another service. Hotmail has earned a poor reputation in recent years, thanks to a number of hacks and poor spam filters, and even though Microsoft has since improved the service the name itself has been somewhat tarnished.
 
Outlook.com, however, is a brand new service, effectively the inheritor of both the Hotmail web service and the Outlook software. It has been in beta for some time, but officially launched a few weeks ago. Hotmail users will be upgraded to Outlook over time.
 
Microsoft also apologised for the incident and stated it takes outages “very seriously.”
