=Completion, Thu Nov  8 01:38:54 STD 2018

This maintenance is now finished.  Further reboots for HA VMs will not be required, and all have returned to service.


=Update, Wed Nov  7 23:36:22 STD 2018

This maintenance will be extended tonight, as workflow has been slower than predicted, but impact to individual VMs is still minimal.

I will update this post when it is complete, or if we'll be dividing it into separate nights. 


=Update, Wed Nov  7 21:18:28 STD 2018:

Some corrections and revisions:

This will actually impact all self-managed HA cloud servers as well.  If you are not on our Hyper-V cluster, you will not be impacted.


-Servers will be updated and rebooted at the same time, with the exception of those that are part of a highly available application cluster of their own.

Servers will be updated 10 at a time, with the latency of the underlying storage monitored closely during maintenance.  I still expect maintenance to be over within 1-2 hours, and individual impact will still be minimal.


We will begin, as scheduled, in 10 minutes.

Date: Wednesday, November 7, 2018
Time: 9:30PM - 10:30PM


Purpose of Work: 

We will be updated the VM configuration version for all HA cloud servers, tomorrow night.  

Impact Of Work: 

Procedure will involve a graceful shutdown, a 1 minute upgrade process, and the server will then be turned back on.

Customers whose servers are being updated may notice 2-3 minutes of downtime, typically.  We will be monitoring for any server that takes longer than this to boot up and regain services.

Servers will be updated and rebooted at the same time, with the exception of those that are part of a highly available application cluster of their own.



We will let you know if the maintenance ends ahead of schedule, or else update you regarding the status of this maintenance at the end of the scheduled window, with further information being forwarded to specific customers, if required.


Rescheduling:

If you would prefer to schedule your server reboot to occur at a specific alternate time, and have confirmed that you have one or more Fully-Managed Highly Available Cloud server ( that do not meet the previously specified exclusion criteria ), please reach out to [email protected], or submit a ticket via our helpdesk, and specify your desired alternate update time before the scheduled update time.
