Well looking here: http://www.dnsstuff.com/tools/dnstime.ch?name=jaray.net&type=A shows that folks shouldn't have any problem at all connecting to any of our services. Record is: Domain Type Class TTL Answer jaray.net. A IN 3600 64.66.96.66 Looking up at ns1.famhost.com.... Reports 1 A record(s). 88ms. Looking up at ns2.famhost.com.... Reports 1 A record(s). 87ms. Average of all 2 nameservers: 87ms (plus 5251ms overhead). Score: B+ Of course one could try a trace route to dibu.com to see where the connection fails. ~Rick _____________________________________________________________________ Virus Scanned and Filtered by - http://www.FamHost.com E-Mail System.
