Re: Backing off
If the database failed and had to be restarted then the caching machines just sat there and tried to authenticate as fast as they could.
I did some training at a technical institute many years ago. Recovery from a network outage was a very painful process - the machines we students had were all disk-less, and hundreds of students trying to re-boot net-booting computers at the same time...... (Back in the 311 days, when it would've been rather difficult to stop someone messing with c:\windows on a given machine).
