The fed has had an increase in security and it is much easier to be spotted, don't attempt to rob it unless you are ready to fight some cops. The fed instantly going to elevated is not intended and had never happened during testing and when I attempted a robbery on live servers did not come across this issue.
I was able to make it 34% into a vault before sounding the alarm, and just fyi I worked on the fed stuff so gen and azeh probably cant help you there.
