Grunff and I are in the process of shifting the wiki and FAQ to a new server. Part of this change requires changes to the DNS records for the sites. As a result you may run into some access problems over the next
48 hours as the changes can take a little time to ripple through and be consistent for all users and ISPs.
Also I would suggest you refrain from making any wiki changes for a couple of days, since you won't know if you are updating the new site or the old one - and changes to the old one will probably be lost since its database has already been copied over.
Sorry for the inconvenience...
