One of the great features of our new infrastructure is that we can migrate a server from one piece of hardware to another seamlessly. This allows us to perform maintenance without downtime, etc...
Unfortunately the networking cards in the new hardware were not properly updated to the latest version resulting in some weird latency issues every once in a great while. We've been monitoring both servers on a second-by-second basis since we resolved the LiteSpeed issue and the server has been stable.
The issue comes in when we do wish to seamlessly migrate the server - the host goes unresponsive for 30 to 60 seconds as the network interface crashes and restarts.
We will be bringing down the S1 and R1 servers tonight for approximately 5 minutes [as long as it takes to shut down and boot back up] to update the networking firmware after which we should be able to perform maintenance in the future without any scheduled downtime whatsoever.
We expect to begin around 9 PM ET and expect the downtime to be no greater than 5 minutes. We do apologize for the growing pains we are experiencing with this new hardware - it's a completely new setup from what we have run for years and we're running into small edge issues that we didn't anticipate.
If you have any questions about this - let us know. We'll keep it as seamless as possible - and there is nothing for you to do / that you need to do.
