Dear Customers,

We have scheduled following emergency maintenance.

DATE: August 13, 2019
TIME: 9:00 PM - 2:00 AM (Mountain Time)

After the network incident on August 12, 2019, we have some critical tasks that we need to carry out this evening to restore redundancy to
our network core.

* Restore redundancy to our dist3.denver2 switch stack.

* Upgrade JunOS on our dist3.denver2 switch stack to the latest JTAC recommended JunOS.  

Impact of Work:
This work will impact our clients in two distinct manners:

* If you are hosted on a virtualized environment on the WEHOSTVPS2 Hyper-V cluster, we will be shutting down all virtual machines within this environment at the start of the network maintenance.  This cluster is most dramatically impacted by minimal network disruptions, and when things go sideways, they require hours of manual intervention to bring hundreds of VMs online, which are generally in an unclean state, require chkdsk/fsck, or have severe file system corruption.

* If you are a private cloud, colocation, or dedicated server customer, you will experience network disruptions up to 15 minutes in  duration during this maintenance window. Theoretically, it should be possible to do the work we need to do with very little network impact, but after the events which transpired on Monday, it's hard to say that with any level of confidence.

We will update this post regularly during the course of our maintenance.  Please contact us with any questions.
