DNS lookup error

Receiving "DNS lookup error" on my Hughesnet satellite connection. Found out my ISP sometimes has trouble with .org domain translation, so I thought it was that, but I was able to connect to craigslist via an online proxy from proxy,org so it's a problem other than my ISP, I think. I think C/L may have reconfigured their DNS servers wrong, or they've implimented a blocklist to certain IP's, which sucks b/c I'm always on a shared proxy address.
