I can answer for the first 2 reported problems.
1. The site got really slow because for some reason the web server started forking out a new process for each request, and would spin that process w/o it ever ending. This server is also a mirror for several large sites, so do that a few thousand times, and things get rediculously slow. Fixed.
2. One of the server admins accidentally had a typo which caused the system clock to skew forward a few hours. Since it was so far ahead and out of the tolerance band for ntp to correct it, it went on for a few hours until I realized the clock was off. Fixed.
It seems like yesterday was one of those embarrassing days where everything seems to go wrong.
As far as the PM thing, that's probably one to ask the webmaster for this forum about.
