TekSavvy → Re: Google DNS versus ours

Alright, all servers are in production now

Comparing our servers, 206.248.154.22 and 206.248.154.170 to OpenDNS and Google

And the clear winner is us

I should probably add that this test is being run from my house from a normal DSL connection, this isn't something that's being run right next to the server that would yield an unfair advantage.

Here on the we(s)t coast, Google's DNS is the clear winner.

dig teksavvy.com @8.8.8.8
shows a query time of 25 msec.

whereas,

dig teksavvy.com @206.248.142.222
shows a query time of 74 msec

That's because Vancouver has separate DNS servers.

You need to use 76.10.191.198 & 199

Just did.

Got a query response time of 76 msec and 75 msec, respectively, compared to 33 msec for 8.8.8.8.

mtr reports a ping of 13 msec, so maybe the server is just under heavy load.

Gabe responded to you earlier. you have to use the Vancouver DNS servers since you're in BC..

That's because Vancouver has separate DNS servers.

You need to use 76.10.191.198 & 199 (these servers are not yet updated though)

we too can make our IPs respond no matter where you are but we just haven't done that.. there's no real need.

Google has that 8.8.8.8 block anycasted.. it's a routing trick.. that make all the routers think that IP is really close but in fact there are srvers everywhere with the same IP...

There's no reason TSI couldn't anycast the DNS server IPs so that the same DNS IPs are used anywhere in TSI's territory :P Of course, that's kind of pointless since the vast majority of people use DHCP/PPPoE to automatically set the DNS servers anyhow. Most of the people setting theirs by hand are DNS ricers :P

well.. there is one good reason.. and well, it's that it would take a bit of lifting to do it and make sure it's done right and for what? not much value..

we'd have to move everything else off that class C...
