Dear Customer

We will be applying latest Critical Windows Updates & security patches on our Hyper-V host machines which will require HV servers to be rebooted multiple times. This maintenance will be starting from 27th September 9 PM CST and updates about the progress will be posted in this announcement. There have been multiple security patches issued - one of them being specific to Hyper-V host machine and hence, this needs to be applied ASAP.

This will apply only on HVCH01, HVCH03, HVCH04, HVCH05 & HVCH09 only. You can read more about the exploit (and patches mitigating it), here: https://help.softsyshosting.com/en/announcements/article/zero-day-emergency-security-patching-for-windows-servers-september-2019

Estimated time for each host machine: 50 to 90 Minutes
Update: Since we have a good amount of HV's, they may not all be completed same day and will be rolled over to next night per time zones of respective server locations.

With regards to VM’s hosted on HV's, All VM's will be shut down when Windows update process is started and will be started / returned to service after all updates are applied / installed.

Thanks in advance for your understanding & co-operation.
