The main board was refusing IPv4 packets as of 00:40 UTC on Sunday, September 4th. This means that, for most people, going to disc.yourwebapps.com to reach the main board didn't work. However, the underlying server appears to still be up if you connect to it with IPv6. One such IPv6 address is 2600:3c02::f03c:91ff:fe98:54ea, which means you can reach the Board with the following link (copy-paste it): http://[2600:3c02::f03c:91ff:fe98:54ea]/Indices/199610.html

However, this will only work if you have an IPv6 connection. See this test to see if you do.
