The Public Utility District No. 1 of Okanogan County will be performing a service affecting reboot on our core Ciena Optical switch in Tonasket the morning of Saturday, August 28, 2015 at approx. 6:30 AM.  During this time period all Okanogan PUD supported fiber and wireless customers that traverse this switch will be affected while the device reboots. We are choosing to call this emergency maintenance as we have lost visibility into this device and attempts to manage it have proved unsuccessful. It is our determination that this issue is caused by a known bug with the version of OS we are using.
