Interesting that they brought it back up in the reverse order, cycling through the CC freq/channels.
It has been failed and showing 852.61250 (on neighbor sites) as the CC (even though it was not transmitting on any CC) since just after 10 am.
At 4:12 pm, the Stanley Canyon site came back up and was transmitting on CC freq of 852.61250.
Then at 4:15 pm, the CC freq changed to 852.85000 still transmitting.
Then at 4:18 pm, the CC freq changed to 853.38750 still transmitting.
Then at 4:21 pm, the CC freq changed to 853.71250 still transmitting.
Maybe this is the way they bring down and bring back up a site for maintenance.
