The nightmare - just before a major sales event the Application goes down.
It's too SLOW.
User's are complaining - no clues. You have not done any release.
Everything on servers looks OK. DB is fine.
Memory is available - every thing you can think of is fine.
Shit what happened !!!
Adhoc solution - only 4 GB of data - restore on backup application.
At least the show must go on. Lucky enough - not a big problem - can be handled in this idiotic way but cannot think of any other perfect solution - which has to be done in 1 hr. I know Dirty but thats how it works - launch - at least no one knows whats wrong.
Analysis and analysis.
Analysis and more analysis.
And then you know - one network ADMIN- trying to solve one problem. Changed the routing table !!! WTF!!
So another item added to the list.
Before you check anything - check networking too.
