We will be conducting some disruptive maintenance this upcoming Monday at 12:00am MDT 06:00 UTC.   We will be deploying a filter to block BGP keepalives before we start so you should see your sessions close with our route servers and your bi-lateral peers around this time with minimal (if any) impact to your customers.  We expect the maintenance to be complete within an hour and we will send a notification when everything is done.  If you have any questions don't hesitate to reach out.

Thank you,

-Mark
