Probably not the best place to ask if anyone else is having problems accessing the forum, since most people having problems will not see the question...

Presumably whether or not you have the problem will depend on which ISP you use, I have no idea how widespread the problem is.

It appears that at least one of the global top level DNS servers is serving the wrong address for ns1.cerocscotland.com.

It appears that with my ISP (maybe also with others), if the first nameserver returned by the global top level domain server does not point to a working DNS server it fails to resolve any names within the domain.
Whilst not trying the second nameserver is probably a violation of standards there may be a number of ISPs which do so.

Some technical stuff which might help explain the above follows:

I've been having problems with some ISPs too.

My work PC today refused to recognise the forum.cerocscotland.com address. On a Plusnet account I was having problems yesterday/this morning too.

I have no idea what on earth you just said :sick: but I have had problems getting on here too when others seemed to be able to access it fine.

I'm not sure what you said either, but I had problems on my home laptop last night, and this morning it gave me an error when I used my history, but was fine when I came in via the old web address.

I can get on fine from work (!) but can't access from home - maybe it's Firefox..?

The forum has recently been moved to a new server, it may just be that not all ISP caches have cought up with the new address yet.

Try this...

Go to start run, type cmd hit return (opens up a black command prompt window)

type:
ipconfig /flushdns

and hit return

Close command prompt window

Flushing the local DNS resolver cache (i.e. the cache on your machine) will not help if your ISP has incorrect information in their cache.
