Upgrade trifecta

Dave works his magic on our 251st Avenue tower.

Today’s upgrades were uniformly satisfying.

We added significant bandwidth to feed Skip-In Ranch and all the towers in Morristown; plus additional bandwidth to Mockingbird and Rio Vista towers; plus increased bandwidth between the Morristown hub and the 251st Avenue and Castle Hot Springs towers.

In addition, we installed a new northward-facing AP on the 251st Avenue tower to serve the growing number of subscribers located on the east side of Castle Hot Springs Road who can’t access their nearest neighborhood tower (Castle Hot Springs) due to an intervening hill. These subscribers are now benefiting from 8-10dB better signal (about eight times the previous signal), as well as the additional bandwidth available at their tower.

We also corrected a mysterious configuration gremlin that was causing decreased signal to our subscribers in Grantham Ranch.

We hope today’s work will make your Internet experience more enjoyable.

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

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.

Network performance improves

Our recent project to improve the bandwidth of both the Mockingbird/Rio Vista and Skip-In Ranch/Morristown backhaul routes has been successful and gratifying. Installation of improved equipment on the Wickenburg end of both links turned out to be sufficient to reach our immediate target, leaving a future opportunity for further improvement when necessary by installing matching upgrades at the far ends of both links. 

Today’s project to improve signal and bandwidth to our newer customers in Grantham Ranch and the Rincon corridor east of the river was also particularly successful. That area is now served by a new dedicated directional access point located at our downtown gateway.

In spite of all the technical challenges, we are continually installing improvements to help keep our Internet service one you would be proud to recommend. Thank you for your patience and for your support.

 

Problems affecting Mockingbird and Rio Vista Towers

Our downtown feed radio to Mockingbird Tower is now definitely misbehaving. Despite showing good signal and quality, it is not delivering anywhere near the bandwidth it should be. We suspect the unit is undergoing a slow failure mode.

This problem affects subscribers of Mockingbird and Rio Vista towers only.

We have switched to an easier frequency for the ailing radio to handle, and have also activated the backup link between our airport tower and Mockingbird in order to steer more bandwidth into Mockingbird and Rio Vista.

We already have equipment in transit, ordered earlier to replace this unit, scheduled to arrive Wednesday. We expect to have it configured and ready for deployment before Friday close of business. Some brief (~10 minutes) interruptions in service may occur near the end of the week as the new equipment is cut into service.

This situation is receiving our priority attention. We apologize for the degradation.

Yes, we’re working on performance problems

Our router manufacturer issued a software upgrade on Monday to close an “exploitable hole” that put the security of our network and your data at risk. Unfortunately, they issued the fix first in the “new features” release chain, and were delayed issuing it in the “current bugfix” release chain. Unwilling to delay, we took a leap of faith and installed the “new features” release to get the security hole closed as promptly as possible.

Our faith was betrayed.

We are currently re-installing the (finally available) “current bugfix” release with the security patch on all the routers in our network. Since this is technically a downgrade, the installation is much less automatic and much more labor-intensive than the original upgrade, needing to be performed manually on upwards of 200 machines, certain of which are barely communicating well enough at the moment to load the software. We ask your patience while we back out the misbehaving wireless software suite installed earlier this week.

A great week,
 and a great 11 years

This week our tower bandwidth improvement project is for all practical purposes complete. Read on to learn about the improvements we’ve made to our performance in Wickenburg and Morristown… plus a little bit of nostalgia in celebration of our 11th anniversary. Continue reading

Morristown Tower East maintenance Wednesday

We’ve determined from subscriber feedback and subsequent testing that the east sector of Morristown Tower is not functioning properly and is delivering insufficient bandwidth. We’ll be replacing that unit Wednesday morning sometime between 9:15 and 10:30.  This will involve an outage of 10-15 minutes, that should affect only Morristown Tower subscribers east of the 267th Avenue alignment.

Wednesday: interruptions for performance improvements

Since our last post, we’ve been hard at work on a new system to deliver more bandwidth to our four neighborhood towers in west Wickenburg, and to ramp our popular Mockingbird Tower up to the speeds necessary to support our increasing subscriber levels.

Subscribers of all our towers from Mockingbird Road westward may encounter some brief (5-20 minute) network interruptions this coming Wednesday at staggered times of the day, as we perform certain of the equipment upgrades described below.

Here are some details about what we’ve been doing, how far along we’ve gotten, and what we hope to accomplish Wednesday. Continue reading
