Just offering an alternative :)]]> http://www.dslreports.com/forum/remark,20989991 Fri, 22 Aug 2008 11:33:02 EDT Re: [Eastern Ontario] DNS Issues? http://www.dslreports.com/forum/remark,20989630 urbanriot : Yea, switching to OpenDNS will actually make your lookups slower, and is completely unnecessary as we just discussed (as well as discussed in the thread Airwolf posted). Cogeco has two other DNS servers that work fine when one goes awry and if you're experiencing issues when a single DNS server goes down, as we just discussed, you have a problem. ]]> http://www.dslreports.com/forum/remark,20989630 Fri, 22 Aug 2008 10:22:59 EDT Re: [Eastern Ontario] DNS Issues? http://www.dslreports.com/forum/remark,20989245 Verno : I had some issues in the past with Bell/TekSavvy's DNS servers as well and I found the easiest fix is to just use OpenDNS - »www.opendns.com/

They have instructions there on how to change your DNS settings in Windows, Linux, Mac's, Routers, etc. Since changing I've never had a problem with DNS lookups.]]> http://www.dslreports.com/forum/remark,20989245 Fri, 22 Aug 2008 09:03:47 EDT Re: [Eastern Ontario] DNS Issues? http://www.dslreports.com/forum/remark,20988788 Airwolf : Not the first time it's started acting up.

It took some digging but I found where I can specify DNS servers and that fixed the problem. Before my router was randomly choosing which one to chat with.
Attaboy... by design, most systems are supposed to query the primary DNS server then rollover to secondary systems on failure.

Windows, for example, queries the primary DNS server on the primary NIC, the queries the primary DNS server on every NIC, then queries all DNS servers on all NICS three more times until it gives up. This all happens in a matter of seconds. On Vista it's about 18 seconds to do all of those steps until it leads to a complete failure.

So, users with normally functioning machines that are plugged directly into a modem or use a router that passes along the ISP DNS servers to the client machines should never experience a problem if a DNS server fails. Of course, most routers should have that failover routine as well. ]]> http://www.dslreports.com/forum/remark,20985216 Thu, 21 Aug 2008 13:56:20 EDT Re: [Eastern Ontario] DNS Issues? http://www.dslreports.com/forum/remark,20985074 HoboJ : It took some digging but I found where I can specify DNS servers and that fixed the problem.

Just specified the first 2 in my /etc/resolv.conf, all back to normal.

I'm sure they'll fix it when they get the chance...]]> http://www.dslreports.com/forum/remark,20984975 Thu, 21 Aug 2008 13:12:04 EDT Re: [Eastern Ontario] DNS Issues? http://www.dslreports.com/forum/remark,20984762 urbanriot : Yep, also seeing problems with 24.226.10.193. Out of thirty queries it only responded to 7, and those were slow.

However the other two seem to be working fine so whatever is doing your lookups locally, whether it be your router or your PC, shouldn't be experiencing a noticeable problem unless there's a configuration issue.]]> http://www.dslreports.com/forum/remark,20984762 Thu, 21 Aug 2008 12:32:59 EDT [Eastern Ontario] DNS Issues? http://www.dslreports.com/forum/remark,20984680 HoboJ : All morning I've been having weird DNS issues with my Cogeco connection. Firefox and IE are both timing out randomly when trying to grab an ip from the dns. Simply refreshing the page or clicking try again in firefox fixes the error.

DNS1: 24.226.1.93 - 10-20 ping
DNS2: 24.226.10.193 - 1000-2500 ping
DNS3: 24.226.10.194 - 10-20 ping

This also affects games that use a domain name for their master server or game servers. Cheers.]]> http://www.dslreports.com/forum/remark,20984680 Thu, 21 Aug 2008 12:18:14 EDT
