My FiOS 25 Mbps service is so reliable that I don’t bother checking the speed much anymore, but when I do I use Speakeasy. Now YouTube is offering its own interesting speed test. Right-click on a YouTube player to try it, or go to this link.
Lately, I’ve taken to channeling YouTube through the player installed on this site, which provides several advantages for me. The videos I create myself need about 750 Kbps to play smoothly, which is no problem for a broadband connection, but pushes a DSL link hard. I am hoping to add a feature that will automatically detect a slower connection and compensate for it.
