Yes Trisha I noticed the same issue with DNS and opened a thread http://forums.thinkbroadband.com/zen/t/4152131-dns-s...
which were apparent from both a PC and Xbox, as you'll see I was told there were no DNS issues.
I tried a router factory reset which had no effect so switched to OpenDNS which seems to have alleviated the issue.
I suspect its one of those annoying intermittent faults.
