the openarena.ws domain seems to have expired so if you use openarena.ws this is how to get back to using it.
[from davidd]
I got this record back from a dig, asked for help in #rainbow and got the right ip.
openarena.ws. 3600 IN A 68.178.232.99
this points to a go-daddy parked domain.
if you want the real website for sure, add this line to /etc/hosts
(or c:\windows\system32\drivers\etc\hosts with notepad if you use a stupidly licensed OS)
76.74.252.88 openarena.ws
