Aaah, looks like it was a network upgrade. Just saw this notice:
Greetings,Looks like we found our problem. Nothing to do with the server.Planet 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.
Thank You,
Planet Engineering
So Dave....cough up! 😄
