Devachat is very difficult for me to access, I often end up at the reg-123 domain.

A few people are experiencing this. Any ideas what's going on?

Unfortunately our domain hosts, reg-123, decided to reset our DNS settings to their default values, pointing www traffic to their holding page.

This was fixed last night but due to the slow way DNS propagates, problems can persist for a day or two.

If you are still having problems, try doing the following.

Start > Run > cmd

That should bring up a DOS command window.

In that window type ipconfig /flushdns

Am i right in thinking if I bookmark devachats IP rather than devachat.com then DNS errors wont happen?

Correct, but not recommended. You'll likely have login cookie problems daily, rather than DNS problems once every blue moon.
