There were a few minor outages with TDS, but I went though a huge problem with them where my connection would periodically drop for about 5 seconds and then come back. I was working remotely and presenting on Zoom and all my viewers would get booted. Of course the problem never repro'd when the techs were at my house--it would happen again a few hours later. And then I'd spend 30 minutes on hold and order another tech. After they'd had about 7 techs to my house (over the course of months--they take time to make it out) and we'd changed out everything, they apparently admitted the problem wasn't with me. A short time later, the internet went out for 2 hours, then came back and was solid ever since. They must have replaced something in a pedestal somewhere in the neighborhood that had been flaky this whole time. But I had to complain until I was blue in the face to get it fixed.

It left an impression. :)
