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.

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.

Skip-In Ranch: Unscheduled outages

Our Skip-In Ranch tower host is having major residential renovation performed. This has led to a half dozen or so outages to Skip-In Ranch tower subscribers over the past several weeks, as workmen turn off circuit breakers, work on the roof in the vicinity of our mast, or remove and replace our indoor equipment for framing, drywall, and painting work. (Subscribers of our Morristown towers may experience micro-outages when any existing sessions through the Skip-In Ranch long link reroute through the Mockingbird long link.)

We’ve successfully educated the foreman about what breakers and components interrupt our service, to the point where at least the workmen no longer disable us indefinitely. Although we still don’t get advance notification of these outages, they do take pains to keep them as brief as possible. We’re all hoping that this renovation progresses quickly and completes soon.

Construction-related congestion

As you know if you have been keeping up with this blog, we have a new fiber circuit on order from CenturyLink that will double the bandwidth at our Wickenburg gateway to the Internet. While we’re awaiting that installation, we have been planning ahead to ensure that we will be able to distribute this new bandwidth evenly across our entire network without artificial bottlenecks.

Late this week, in preparation, we replaced several of the radios driving our long links between Morristown and Wickenburg with new and faster units. The new radio links are now operating at multiples of the speed of the old, and well over the speeds necessary to distribute the new bandwidth clear to Circle City.

However, despite the speed of the new radio links themselves, the effect on our overall speed on the Morristown side of our network seems to have been negative. We’re extremely concerned (and puzzled) by this result. Although we’ve been able to make a number of tuning changes to evade the worst of these performance issues, we haven’t yet identified an underlying cause.

We’re continuing to work this problem over the weekend, with consulting help as available, as long as necessary to ensure that this temporary disruption is solved expeditiously. We apologize for a less than seamless enhancement experience, and look forward to being able to deliver our upcoming bandwidth increase to you as efficiently as possible.
