Hi,
We have a very strange problem here....
Since Sunday, our company has been experiencing problems with website connectivity.
We have a webserver with 60+ sites on. This is up and running without any problems.
We host client's domain names and some of our clients host their own domains and point them to our server (@ Rackspace). We have checked and we can pretty much 90% guarentee this is all ok.
Here is the problem.

At my office we can connect to all our own sites without problem.
At home 20 miles down the road (on another ISP) *some* of the same sites don't connect at all!? The domains just don't resolve. The same applies to our clients...some can see their sites, some can't. They can browse to other websites we don't host.

Now, I'm pretty sure this is a routing problem and I'd like to think this is outside our control but how can I pinpoint the problem!?
People are saying it's our problem but it can't be accross the board as we can still browse to our sites here and most of our other clients are ok.

Any ideas?
(I never get the easy problems) :mad:
 
They're not involved on the domains themselves (we use namesco for DNS) but our problems coincide with their problems which I find strange. Also, this isn't affecting all domains we handle. Some of our clients point them to our server themselves from various people.

It just seems to differ depending on which ISP you're trying to get to the site from.

You could always get them to use OpenDNS - basically change their DNS servers from their ISP's servers to the ones located here -> https://www.opendns.com/start
 
Cheers for suggestions guys - appreciated.
It's looking like this is a possible Rackspace mess up. The first one I've ever heard of since we've been working with them. They're usually solid as a rock.
 
You really need to understand DNS and identify commonality between DNS servers that the various people are using. Let us know what happens.
