Did you change the IP address for your DNS name recently (skytrackercanada.com)? Usualy it take one or two days for the changes to propagate across all DNS servers... Try to put these instead of your current DNS servers into /etc/resolv.conf nameserver 207.181.101.4 nameserver 207.181.101.5 These are AT&T's DNS servers in Canada, Toronto area, I think they are publicly accessible, although I am not 100% sure. To change the DNS servers is not the best sollution because it may slow down a little bit the resolv process, but atleast you should know about your current DNS servers. What is the Operating System of your Proxy server? --Miro > > Do 'nslookup.'
