One unfortunate exception was UD, which covered the embedded dev room on saturday (sunday it was elsewhere with good traffic) and python and community room on sunday.

Obtaining an IPv6 route took *minutes*. Tried the DHCPv4 network and it was same story there. If I managed to get an address, then the packet survival rate was in the low 30's.

I have no idea what went wrong, not enough APs leading to overload or something else, but performance was really bad.
