Our host will be carrying out a few upgrades to the server so there may be some down time for approx 3 hours tonight.

Here is an extract of the message:

Datacenter engineering will be performing work on all of the SM-CAR6-X routers in the DLLSTX4 datacenter beginning at 11:59pm CDT on Sunday August 22. The work will take approximately 3 hours to complete. While no prolonged disruption in service is anticipated, customers may experience some downtime as a result of routes reconverging and re-configuration of the routers. We apologize for any inconvenience that this may cause.
