I updated from Tiger to Snow Leopard last night and had no trouble until this afternoon. Since 2 pm today I haven't been able to access facebook.com or livejournal.com in Safari, Firefox, or Chrome. I checked downforeveryoneorjustme.com so I know it isn't on their end and my roommates who are all on the same network as me are all able to get to those sites. I've tried pretty much everything I could find, I reset safari, emptied the cache, renewed the DHCP Lease, no proxies are checked in the settings, etc. I don't know what else to try. Any ideas?
