You mean the "three hour internal maintenance (announcement)"? Nope - I've seen nothing else.
Some (including me) experienced a short total shutdown - WGT's URL wasn't available any more. Perhaps they moved to other servers and the public nameservers had to update??
Now, I experience a deja-vu: Local CPU load (and temperature) rises more than just before the update, similar to some months ago. Again, I have to take care to avoid an "overheated" shutdown of my PC.
