Hello!
 
We are scheduling a maintenance window for the R2 server on Friday, September 15th at 10 PM ET [GMT-4] to move the server to our new storage platform.  We are scheduling this window from 10 PM ET to 2 AM ET and we expect the downtime related to this maintenance to be 2 to 3 hours at most.
 
We will be keeping this thread here on our forums up-to-date as we perform the migration and will answer any and all questions you may have about the migration process here or directly in response to the email I will be sending out shortly to all affected clients.
 
While we do apologize for the length of this maintenance window we are sure that you will be happy with the end result.  We have had numerous clients reach out to us after we migrated the R3 server last week to thank us for the upgrade and even a few that only knew it happened because everything was dramatically faster.
 
Should you wish to see more details on why we're performing these migrations as well as some graphs illustrating the performance gains - they can be seen here.

We have passed the half way point for the home directory.   If this rate holds I would for see being done closer to 1m EST for this transfer.

The migration was successful but we are going to restart the server to add more CPU Cores to it [we mistakenly gave it 12 instead of 24].

The R2 server has been successfully cloned onto our new storage and is fully online and operational.

 

We are closing this maintenance window.

 

Thank you for your patience!

Disk Latency for the R2 server is already substantially lower.

I will update this thread with more graphs once a bit more time has passed.
