Morristown upgrade Friday morning; possible Mockingbird upgrade Friday afternoon

Just a brief notification that the upgrade work to the WIckenburg/Morristown link is scheduled for tomorrow morning (Friday) between 9:00 and noon.

Depending entirely on time available, it is possible that similar upgrade work may be performed on the Wickenburg/Mockingbird link sometime in the afternoon, to provide even more bandwidth there. This would temporarily affect network performance to all the towers mentioned in our previous notification, with the addition of Mockingbird and Rio Vista towers.

Thank you for being a part of Grand Avenue Broadband.

 

Morristown Upgrade, Stage II

Tower climber

Dave installs Stage I…

The equipment needed for stage II of the Morristown bandwidth upgrade arrives this week, and we plan to be installing it on either Thursday or Friday morning.

This is the gear needed to complete the “full link” upgrade of our feed from Wickenburg, providing additional bandwidth to our east-end subscribers over and above the “half link” upgrade installed four weeks ago.

Subscribers served by east-end towers may see some short service burps and lower performance for roughly a 20-minute period sometime between the hours of 9:00 AM and noon, as our network compensates for the temporarily missing link by routing Wickenburg traffic over slower alternate routes.

Subscribers of these towers will be affected:

  • Morristown
  • Skip-In Ranch
  • Castle Hot Springs
  • 251st Avenue
  • Dixileta

We’ll post a brief notice like this one once we are certain of the day of installation.

Work continues Wednesday 20th

Last Wednesday’s installment in our bandwidth improvement effort surpassed our expectations. Despite the fact that we had only enough time to deploy half the planned link (due to the structural enhancements we had to add to the tower to handle the heavier equipment), we managed to increase bandwidth to Mockingbird tower significantly via its backup link, plus we determined that the leftover half of the high-speed link could be more effectively employed elsewhere. 

Tomorrow, we hope to be able to install improved equipment on the inbound side of both our Skip-In link (the main line to Morristown and all points east) and our primary link to Mockingbird Tower. As this involves some high-tower work, it will be slower, and some of the transitions may be less than smooth.

Although our existing redundant paths help ensure that your Internet availability will never be entirely severed, you may experience some “brownouts” as our system determines in real time that primary paths have gone black, and temporarily switches to secondary paths that will serve some of our towers somewhat more slowly. Short of unplanned disaster, the perturbations should not persist past 5 PM.

Thank you for your patience as we work to bring speedier Internet access to our ever-growing network of subscribers.

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.
