Hi All

Some of you may have noticed a problem accessing the forum for the last few days.

This was caused by a power outage at a DNS server data center. The datacenters where the Invision servers are located at had an issue that knocked out electricity to an entire building of servers. While Invision had no servers in that particular building, the DNS servers that service them were located there.

DNS servers are computers that route internet traffic. They're what allows you to type in a url like http://www.disabledphotographers.co.uk and end up at our site. Without them you would need to remember long IP addresses to visit websites.

This means if those servers aren't operational, then it can become an issue to try to reach a site by typing in its URL. In some cases the Internet Service Provider (ISP) that you use will cache, or store information that will still allow you to reach a site even if the DNS servers aren't operational.

If you were still experiencing an issue it's a result of the DNS information being cached by your ISP. Unfortunately the only solution is to wait for them to update the information.

I hope that explains things for you.
