They screwed up (extremely slow) with an update for one of my domains and I hard-coded to bypass their DNSes. If one is looking for an option on DNSes to use, you can consider OpenDNS or use Singnet's (165.21.83.88 / 165.21.100.88) PS - Its a lovely Sunday morning .... _______________________________________________ LUGS Mailing list - [email protected] List FAQ: http://wiki.lugs.org.sg/LugsMailingListFaq Info page: http://www.lugs.org.sg/mailman/listinfo/slugnet To unsubscribe send an empty email to: [email protected]
