So we've just had a client register a new domain name, and set up a sub domain that will be pointing at our servers.

In my inbox I got an email informing me of what was set up. Basically, it is of the format:

www.something.domain.co.uk

Where their main website is at www.domain.co.uk

Erm...can that be right?

There are 3 reasons for questioning it. Firstly, I don't think it's right. Secondly, it doesn't resolve yet. Thirdly, it's not being set up by the most tech-savvy client in the world.

May be a really stupid question...maybe I'm just going a bit mad.

to examplify what you've put

www.something.example.co.uk

this would be a technically correct sub sub domain if you like.

however normally you would want a sub domain to resolve to

something.example.co.uk

but they've added an extra depth eg

www.something.example.co.uk

i'd suggest this is not what they want

I agree.

Now I'm trying to second-guess what's gone on - whether that is the actual address set up, or whether it's just been communicated badly.

maybe a silly question ... but maybe as you said they have just miscommunicated to you ...

does something.example.co.uk resolve?

Not a silly question - but I did try that as well. The same problem. What's odd is that it's not a 'server not found' error (or in fact a redirect to their main site, as they have with sub-domains that definitely do not exist), but rather a 500 Internal Error on their host.

Good. Then the problem is between them and their host. Unless you've got formal authorization to act on their behalf, you couldn't do anything if you wanted to* ;) If it were a DNS issue you'd never even get that far.

But you need to look at the error logs for more information. Even at the generic shared-hosting level, error logs will generally tell you enough to diagnose the problem.


* Assuming for the sake of discussion it isn't one of those "What's a browser?" clients. If so, it will be faster to get authorization and do it yourself than to explain what to do.

Well, mystery over. The address without www. at the start is now resolving to our servers.

I doubt I'll find out what changed, but everyone's happy campers now, so I'll just leave it be.

Glad I didn't have to get involved with their host - that always seems to drain hours and hours away.
