Customers may have noticed slow page load times since www2 was replaced, this has now been resolved.
Whilst removing the old www2 from the rack on Tuesday (and 2 more machines which were not required any more) we moved the private LAN switch up the rack and reconnected it. This was due to it being removed to give space for the new R200 servers we installed a few months ago, but now there is space we relocated it.
Unfortunately when we did this, one of the cables was plugged back into the switch, causing a storm on the switch. We also missed the cable for www3's private lan. This caused the firewall's CPU to overload, causing the slow access (and also for some customers to require database IP's on www3 changing temporarily.
We apologise for this service interruption, and will be replacing the firewall in the new year and at the same time re-labelling and replacing cables in the rack. This will require a few hours of downtime, which we will notify you of dates after the Xmas break.
The new firewalls are a redundant pair also, to avoid the problem we had a in October.
