i got a mail from Killer creations this morning
"Dear customer
At 05:00 am tonight (2nd July) we will be installing a new Cisco WS-X6748-GE-TX card into our Centro based Cisco 6504-E router. This module is designed as a high capacity fabric enabled card providing 40Gbit/sec of internal switching.
Downtime is only expected to be around 2 - 5 mins as cables from existing core switches are migrated direct into the new card.
Apologies for the late notice, this was originally scheduled for next week but has been brought forward to avoid a conflict with one of our network peers (Tiscali) also performing updates in the later part of next week."
i dont think it will effect many people and i have to hand it to killer creation they seem to be carrying out a serious amount of work on there servers/network which for us is great
