Downtown Tower Upgrade

We will be replacing the aging and increasingly problematic service radio atop Downtown Tower late tomorrow morning (Wednesday 10/10) with a new and faster unit. Expect an outage of 10-15 minutes as the old unit is unbolted and the new unit secured. This outage will affect only users served directly by Downtown Wickenburg Tower — subscribers served by all other towers will be unaffected.

Tower slowdowns

We’re experiencing an issue with some of our towers in which the speed to subscribers degrades as equipment uptime increases. Towers identified so far have included Skip-In Ranch Tower, Downtown Tower, and all three APs on Morristown Tower. ┬áIn all cases, power-cycling the radio unit restores full performance.

Our equipment manufacturer, MikroTik, suspects a memory leak in their OS, and has asked us to provide them with diagnostic dumps from the affected equipment, which we are in the process of assembling for them today.

While we wait for a response from MikroTik, we’ll be setting up an automatic powercycle schedule on the affected towers. This will result in an approximately four-minute interruption of service between 2:00-4:00 AM several times each week at these towers. We hope to have this periodic refresh cycle operational by Monday.

Brief Downtown Tower outage Tuesday

Recently, we determined that our Downtown Wickenburg Tower was exhibiting impaired performance depending on how long it was continuously operational. While awaiting the manufacturer’s diagnosis, we put a script in place to reboot this unit in the wee hours every four days, to keep it operating at peak.

The manufacturer replied today with the suggestion that reinitializing the unit from scratch should return it to proper operation. We’ll be performing this procedure around noon on Tuesday (tomorrow). This will result in a service outage of 10-15 minutes, which will affect only users directly served by Downtown Tower. We hope this will result in improved performance for our Downtown subscribers.
