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

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

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.

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 Improved

As of about an hour ago, we believe we have found our issue with Mockingbird Tower Central, and taken steps to provide immediate improvement. Although speeds are not at the level they were three weeks ago (due to suspected antenna hardware damage and pending part arrival and replacement), they should be greatly improved over the degraded performance seen over the past week. Please drop us an email if you are not seeing adequate performance for your equipment.

Technical details follow for the curious.
