So after investigating the downtime, it turns out to be our provider that started the issues...

"NFO is planning to upgrade the version of Xen on your machine to the latest version at 1am CST on March 5. This new version offers various bugfixes, performance improvements, and security fixes over the current version that your machine is using."

As a result of the maintenance, you will see your server go down for approximately 10-30 minutes, then boot back up. If you are running Windows 2012 R2 or later, your VDS may need additional reboots to work properly, due to a bug in older Windows Xen drivers related to how it boots up (that only occurs during bootup)

Amazon did a forced reboot also...
The process C:\Program Files\Amazon\XenTools\LiteAgent.exe (UOEVOLUTION) has initiated the shutdown of computer UOEVOLUTION on behalf of user NT AUTHORITY\SYSTEM for the following reason: No title for this reason could be found

(D)DoS attack against your service
Our system responded to a (D)DoS against your service with a filter on chicago-router-1.

Target address: 216.52.148.101
Attack: a UDP flood of length-1428 packets/3
Filter duration: about 4 hours
This is what caused a DNS issue and a log in issue for some players

AND if that was not enough, the forced reboots caused a save error that had to be manually loaded...

Good new is the last save could be recovered and there was no revert!
