id Software's Graeme Devine updated his .plan with word of problems on the Quake III Master Server, and some temporary down time that it's causing:

The Quake 3 Master Server

Due to an ongoing flood attack on the authorize server the master server got super slow on responding. For a few weeks we've noticed that it was less than solid, but it wasn't until investigation that the cause was found. Apologies for this.

I'm working on the issue right now, so the master server may appear down today for a few hours starting right about now.

Graeme.
