We're hosted for free on a busy server that supports some critical ubb.x sites, we shut ourselves down when server load jumps to help when possible. They have taken some steps this am to relieve some of that load, turns out some hardware (memory) died and needed replacement.
Donate to UBBDev today to help aid in Operational, Server and Script Maintenance, and Development costs.
Please also see our parent organization VNC Web Services if you're in the need of a new UBB.threads Install or Upgrade, Site/Server Migrations, or Security and Coding Services.
