it's a case of everything gets routed through "OpenDNS" ?-tomos (April 24, 2008, 08:08 AM)

That's not quite how it works.

* Your system knows the IP address of a DNS (perhaps OpenDNS's)
* You enter a host name (e.g., "www.donationcoder.com") into your browser
* Your PC doesn't know the IP address of that server, so it asks the DNS (you can do the same thing manually via the nslookup command)
* The DNS looks it up in its database (maybe asking an upstream provider for help), and returns the IP address (in this case, 208.101.58.90)
* Your browser then sends an HTTP request to the IP address that it just gotSo you can see that the DNS is only returning an address, not acting as a go-between for you and the server.

(And there are multiple layers below this, including TCP and UDP, and routing with IP addresses and MAC addresses, but that just clouds this question)

So when Mouser says that OpenDNS is having the problem, he (presumably) means that the route that the network chooses to get from his PC to the DC server has the same problem as the route from his PC to the OpenDNS server. Presumably they both pass through the same router at some point, and that router is illin'.

I'm not sure if this is related, since DonationCoder has been working fine for me, but YouTube is loading awfully slow for me today.

Tracert shows 3 timeouts before finally getting to YouTube.com

;D

would be interesting to hear what did happen .. or why - they thought it was AT&T this morning then saying it was some "backbone" (Dallas)

Josh:
This just in!

Server maintenance personnel at the hosting company for DC noticed an unusual odor coming from the rear of the server. Upon further investigation it appears that Cody may have pooped on the network cable causing unwanted Ethernet packet collisions thus slowing down access to the site or denying for some.

We will keep you posted as more develops
