CenturyLink Outage Plan

CenturyLink has informed us of a 15-minute service outage planned for next Wednesday (the 15th), sometime between midnight and 6 AM. This will affect all subscribers.

CenturyLink maintenance schedules typically change once or twice as the original announced date approaches. If this happens, we will publish a corrected posting.

Thank you for using Grand Avenue Broadband.

Nasty KRACK

This week’s networking crisis is that black-hats have found another way to violate your privacy. Called the KRACK exploit, it allows hackers to spoof WiFi protocol so as to break its encryption and read your traffic.

It’s worth pointing out that this is not just a zero-day bug in some manufacturer’s implementation—it’s a defect in the WiFi standard itself, and all WiFi (802.11) encryption is vulnerable to it. It does require a hacker to be close enough to have physical access to your radio signal.

We wanted to let you know what we were doing about it, and also what you should be doing about it yourself. Continue reading

West-side upgrades Wednesday 10/11

Subscribers served by Constellation Tower (this includes subscribers served by Diamondback, County Line, Black Mountain, and Easy Street Towers) will experience several short micro-outages around mid-day, as equipment and cables are swapped to upgrade Constellation Tower to gigabit bandwidths.  The outages will affect almost all Wickenburg subscribers west of Burger King (except for those served directly by Mockingbird and Downtown Towers), and should last at most a minute or two; several micro-outages will occur before work is complete.

Watch for a posting later on this week in which we will discuss the infrastructure improvements we’ve been making over the past month to provide you faster service.

Good news (for a change)

As a result of a long-term project accomplished earlier this week, subscribers are now seeing faster speeds and improved response times. Most subscribers are experiencing sustained speeds exceeding their contract limits (some are seeing double their contract limit), with an additional speed boost layered on top whenever possible for brief, non-sustained transactions such as web surfing.  Continue reading

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 recapped

I’m happy to report that, as far as we have been able to determine, all our speed-related problems at Mockingbird Tower are now resolved. Assuming this announcement doesn’t generate a spate of contrary responses, our next task will be to arrange for incremental UPS protection at our towers, beginning with the ones that are most highly subscribed; and working with our consultants to assure that we can deliver to our subscribers all the untapped bandwidth currently available at our Internet gateway.

For the technically curious, a brief description of the source of our speed problems appears below. (Warning: unpaved roads ahead!) Continue reading

Mockingbird improves…

We found and corrected the source of the frequent four-second timeout pauses. Mockingbird subscribers will now at least be seeing consistent data delivery, just not yet at the speeds we would like to deliver. What the tower is delivering right now should be fine for browsing, mail, and even a Netflix movie, but heavy data demands like Windows/Mac updates will still take longer than usual.

We are continuing to work on the speed problem with our dedicated and knowledgeable consultants.

“Big Sleep” to blanket Mockingbird tonight

After last night’s testing, we suspect the most probable cause of the performance problem at Mockingbird is a bad customer roof unit radio hashing our tower. We’ve exhausted all the minimally invasive tests we can run. Starting tonight, we’re running a Big Sleep test on all our Mockingbird subscriber units. Continue reading

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
