I've been reading the "${VENDOR}'s support has really gotten worse lately"
threads for pretty much every vendor for the past twenty years. That's not
to say they've all been wrong. But it reminds me of those quotes you'll see
about how "these kids today are awful and society is going to pot" and then
the big reveal is that it was written in the 1950s, or 1920s, or just
before the peak of Rome, or something like that. The general tendency for
people to view the past as the good ol' days.My most memorable Cisco TAC disaster story. Taking away "configure" from TAC wouldn't have saved us. The guy simply reloaded the switch without asking. The core switch for a building with hundreds of end users. In the middle of the day. The building with most of the C-level execs. Our management was pi-i-i-issed. That got escalated pretty high, pretty quickly. And quick policy change that we did not give TAC keyboard control. This was about ten years ago.
