We will be performing Emergency maintenance on our network starting at 12:01 AM Wednesday March 20, 2019.


The maintenance will begin at 12:01 AM and should be complete by 6:00 AM Thursday morning. The actual estimated time is about two-4 hours but the window is from 12:01-6:00 AM. The maintenance is not expected to be service affecting but the possibility exists. Please note, we will make every effort to minimize any and all interruptions.

If you have a failover internet circuit available, you may wish to insure it is operating properly and ready for use should you need it.


We appreciate your understanding in this matter and thank you for patience while we resolve this issue!
