This went by in a previous posting I made:
Ookla may have made themselves long term irrelevant by their recent
behavior. When your customers start funding development of a replacement
(as Comcast has), you know they aren't happy.
So I don't sweat Ookla: helping out the Comcast test effort is probably the
best way to get bufferbloat in front of everyone, and best yet, the code
for the tests is out there.
