Internet disruption Friday, 1/17 4:00 PM for upgrade

Internet service will be interrupted for approximately 10-15 minutes on Friday, January 17 after 4:00 PM so that we can perform upgrades. Please plan accordingly. I apologize for any interruption.

This upgrade will increase our usable Internet bandwidth from 100 Mbps to 500 Mbps. This should alleviate the slow performance of many Internet-based services. Some have asked if this will make all Internet access faster, or if it will just make things "not as slow." This is a nuanced question, and the answer is a bit complex, but I'll answer it using the Beltline highway as an analogy.

Our Internet connection is like the Beltline. The speed limit is 55mph, and if there are only a few people using it, everybody can go 55mph. But at certain times like rush hour, so many people are trying to use it that everybody slows down. If we were to add 8 more lanes to the Beltline, the speed limit would still be 55mph, but even during rush hour, most people would still be able to go 55mph. So adding lanes isn't the same as increasing the speed limit. 

Our Internet connection is similar. The maximum speed is limited by many factors, such as the capacity of the servers on the other end to send out data, and the overall speed of the Internet as a whole. During school day peak usage times, so many of us are trying to use it that we all slow down below the maximum speed. Adding bandwidth makes it possible for more simultaneous users to achieve the maximum speed.
