It seems that our friends at mtbs3D.com are currently experiencing some technical issues with the hardware in the server hosting the website, so the site is currently down, but hopefully it will soon be back online. Below you can read the official announcement about the problem from Neil Schneider posted on the MTBS3D Facebook page:
MTBS has been down because we had an absolutely HORRIBLE server crash. Despite making backups, this would have been very damaging especially since we’ve been making new service updates for the site that hadn’t been mirrored yet.
Fortunately, the hard drive was mirrored by RAID, and we are taking steps to get things back to normal. Don’t forget about us in our absence. I don’t have an ETA yet – we’ve never dealt with something this severe before…but we are on the case!
Update: MTBS3D.com was back online for a bit, and then back offline unfortunately due another problem.
