After our DDoS attack the day after upgrade, I'm sure we're all somewhat paranoid about the site being slow, and that's the case today. The evidence on hand however points to a wider problem that's currently affecting parts of the UK and elsewhere, which has already been reported on by the Beeb and the like. it's causing problems for a lot of sites, as yet again a DDoS attack has been used to target some big company and take their resources offline.
Bear with us (and everyone else affected) until we're back to usual speed if you're affected, and in the meantime I'll keep monitoring the situation to ensure that it isn't us! :)
