251st Avenue tower outage Wednesday

Due to a recent real-estate transfer of the residence at which our 251st Avenue tower is located, we have been instructed to remove our tower.

We have already secured a commitment from a neighbor and long-time subscriber to assume the duties of neighborhood tower host, so we will be moving the tower to its new location during the day tomorrow (Wednesday). This will result in an outage of two to three hours for those subscribers and satellite towers served by 251st Avenue Tower, as the physical tower itself must be disconnected, detached, uprooted, transported, re-erected, cabled for power in its new location, and have its inter-tower feed links properly realigned.

After the relocation, we’ll be re-aiming the roof units of our closest-in subscribers first, then the farther-out subscribers as necessary. Our furthest-out subscribers in the vicinity of Circle City will likely require no re-aiming at all, though all signal levels will be compared before and after the relocation.

We apologize for this service interruption, and wish to assure you that we will be performing the relocation expeditiously, in order to resume service as promptly as possible.

Mockingbird testing progresses

Mockingbird TowerCondensed version: We’ve narrowed down the Mockingbird Tower problem to RF noise that spikes periodically. Our tower equipment and configuration are clean and validated. We now need to perform after-midnight testing over the next few days that will result in brief (10-20 minute) interruptions of service for a number of the subscribers on this tower.

Details and analysis follow for the technically curious. Continue reading

Mockingbird Interruption

Subscribers homed to Mockingbird Tower (both Central and West) will experience a short interruption of service tomorrow (Tuesday) morning, as we rotate the mast down to replace the radio and pigtails for the Mockingbird Central antenna in order to attempt to alleviate our recent performance issues. We will also be correcting the tower’s cant at this time.

Should the problem turn out to be in the physical antenna itself (a much lower probability, but possible), time will be required to locate and ship a replacement for this unit, which appears to be in short supply due to a manufacturer merger. If this is the case, we’ll keep you informed via this blog.

Brief outage Friday midnight

This announcement affects only subscribers of our towers located in Morristown and Wittmann. Subscribers of towers located in Wickenburg (including “postal Wickenburg”) will not be affected.

We are replacing the Network Operations Center router in Morristown with a faster and more powerful model. There will be a brief network interruption on the order of 10-30 minutes just after midnight Friday night (i.e., Saturday morning) to cut over power and cabling to the new router.

Mockingbird, Easy Street upgrades Monday

We were quite pleased with the smoothness of today’s whole-network speed upgrade, coordinated between and performed by us and CenturyLink, resulting in under 60 seconds of downtime at 7:30 AM.

Our next task is to better distribute the additional speed among our towers. To that end, we’re spending Monday on upgrades to Easy Street and Mockingbird towers. Continue reading

Tower Maintenance: 251st Ave.

We will be increasing the capacity of 251st Avenue tower this Tuesday, December 12, between 9 AM and 2 PM. Users served by this tower, as well as by Dixileta and Circle City towers, may experience brief (<10 minute) outage periods as equipment is detached and replaced. Users served by Castle Hot Springs tower may experience mild slowdowns as data is shunted through that tower to serve 251st Avenue during times when the primary link units to 251st Avenue are being replaced.

Brief outages at Diamondback Tower

The demand for service from Diamondback Tower (neighborhood POP), over just the few months it has been available, has been both surprising and gratifying. Because of the fast subscriber growth on this tower, we’ll be spending most of tomorrow (Tuesday, 10/18) replacing the small-neighborhood service equipment with a more sophisticated three-unit tower capable of delivering a cleaner signal and more efficient service to the entire northern North Vulture Mine area.

We’ll be relocating the existing unit a few feet away, and leaving it in operation while we erect the improved tower. We’ll perform the cutover once the new tower is ready for service. Subscribers should see only two or three outages throughout the day of about a minute or two each as cables have to be extended and reconnected, and the old tower feed has to be re-aimed at its new location..

Our thanks to all our Diamondback subscribers for helping make our neighborhood venture there such a rousing success.
