In a statement, Microsoft claimed that the outage was caused due to its developers implementing bad code.
Overruling Protocol
Microsoft developers it seems, were working to iron out a bug in their software.
The solution to the bug solving, apparently caused the massive outage of Azure cloud services.
Microsoft said that it had tested the update before rolling it out.
The Azure data center in Dallas suffered a complete outage for a short while.
Data centers in Europe didnt recover until deep into the following day.
The configuration switch was incorrectly enabled for Azure Blob storage front-ends, wrote Zander.
The update proved itself in every test in the alpha testing phase.
The result as seen on Nov, 18 was a all out outage causing problems to users.
Zander acknowledged that cloud operations must become more reliable and said Microsoft will continue to work on that goal.
