We started getting the wave of complaints over the last two weeks or so. Perhaps up to a month ago was when the initial few issues that were reported but were chalked up to being “an issues out on the internet.” Did your issues in CT start on a certain date? -- Nick Zurku Systems Engineer

Hello all, I would appreciate if someone from Comcast could contact me about this. We’re having serious throughput issues with our AS20326 pushing packets to Comcast over v4. Our transfers are either the full line-speed of the Comcast customer modem, or they’re seemingly capped at 200-300KB/s.
