The map is being hosted on a separate server now to try to improve game experience. It can be found at tekkitcrunch.com/map. It has to re-render though, so it won't be too useful for a couple of days.
Also, I noticed that the rules here don't match the /rules
[1] Be respectful of other people's work
[2] Don't grief
[3] Don't tick off the admins
[4] Don't hack in items or dupe
