Yeah, it's been something that seems to be very sporadic and not really anything we can easily nail down; might well be ISP-related issues at the end of the day, or other problems with the general state of the intertubes in various places. Unfortunately our Operations department hasn't been able to nail anything concrete down yet based off of the information we've been given, but if and when we figure anything out I'll make sure to pop back in and inform you guys. =)
