Colorado Springs DTRS Towers Down?

Is it my radios or are Cedar Heights, Silver Heights and Ski Summit towers not working? Did they change control channels, maybe?

Cedar Hts looks like it is down but all others are up with the same control channel freqs. At 11:49 I got a message saying Cedar Hts "site control path down".

And interesting traffic on EPSO TG-1 for the search for the armed party in Widefield. I am hearing it on Stanley Canyon.

And that site down message said it was user initiated so probably doing maintenance.

Cedar Heights is back up now (as of about 1:45 pm).

I see Cedar Heights back but Silver Heights and Ski Summit remains down!

My thoughts are that Silver Heights would be on some type of alternate control channel if they aren't on the primary. If it isn't on the alternates, then the database should have all the frequencies that Silver Heights was known to be using up until late August if you would like to browse through those for a control channel. I believe the state has been doing some repeater replacements and it is possible that they rotate out the control channel in order to replace it.

The only for sure way of knowing that a site is down is to check one of the neighbors with something like Pro96Com to see if it lists the site as down. It would be pretty detrimental for Douglas County if Silver Heights was 100% down as it provides a very significant amount of coverage for central and parts of the southern end.

That's strange. I see them fine as neighbors off of Stanley Canyon.

Stanley Canyon shows connected neighbors:
Silver Hts 853.525 cc
Cedar Hts 860.8125 cc
Ski Summit 859.9625 cc

Also have Cedar Hts coming in good on my 396XT and Pro96Com with eleven Zone-4 neighbors connected and traffic coming through.

I'll try to pull in Ski Summit and Silver Hts when I get back to my scanner/computer (as I cannot remotely change the control channel freq on my Pro-106 connected to my Pro96Com).

Getting Ski Summit just fine with traffic as well. On my Pro96Com, Ski Summit also shows Cedar Hts as a connected neighbor.

Just FYI. Ski Summit (site 413) went down at 11:21 this morning and is still down.

It is back up now. That wasn't routine maintenance though. Their maintenance guys got an alarm over their WAN about it:
