Okay, after messing around for the majority of the day, the Overpoch server and the ArmA 3 Wasteland server are now back up and running.
The ArmA 3 server seems completely fine. (Feel free to find problems and report them here.)
The Overpoch server has several small problems you'll have to work around:
1: The database was wiped. Yes you've lost your base, your gear and your questionable Humanity values. Time to start anew! Stop moaning and get on with it.
2: The Battleye filters might need tweaking. Post here if you get kicked. Tell us exactly what you were doing/interacting with. A error code and rough time of kick will also help us the fix the problem much faster.
3: The Overpoch traders in Stary, Klen and Bash (the scientist-looking/spaceman dudes) are a little bugged. You probably won't get the option to trade with them yet. I'll fix it tomorrow. -Fixed
4: Speaking of traders. I've added in as many Overwatch weapons, ammo and vehicles as I can for now. If you find something that's missing post it here. Be specific with details and provide a screenshot if you don't know the name of something. One of the Admins will add the missing item to the database when they get time.
5: The Overpoch tools we offer have had their configs updated and should be working fine, but to use the Donor page you'll have to re-register. Remember to check your spam folder for the confirmation email. Post here if you don't get one and I'll activate you manually.
That's all for now. I'll amend this post tomorrow evening after work. Updates will go at the top of this post.
