Let's "Unspin this"
"As part of a performance update to Azure Storage, an issue was discovered that resulted in reduced capacity across services utilizing Azure Storage, including Virtual Machines, Visual Studio Online, Websites, Search and other Microsoft services," Zander told the Northern Hemisphere.
"During the roll out we discovered an issue that resulted in storage blob front ends going into an infinite loop, which had gone undetected during fighting (testing).
"As part of a performance update" = the rest of the comment I am going to give you is utter bullshit
"An issue was discovered that resulted in reduced capacity across services utilizing Azure Storage" = No shit, the users discovered this faster than the tech's, It's easy to "discover an issue" when your phone-line is being burnt down about it.
"During the roll out we discovered an issue that resulted in storage blob front ends going into an infinite loop" = Data does not go into an infinite loop, the commands dealing with it can, if they are ill-conceived. i.e. : I detect a change, send me the new file thus I detect a change send me the new file
"which had gone undetected during fighting (testing)." = It wasn't tested (at all) properly
