Comcast posted the fastest average speed of all major Internet Service Providers in December, according to Netflix, which publishes monthly speed rankings of both small and large ISPs.

The cable operator’s rise to the top comes a few months after it announced a partnership with Netflix to offer the streaming service’s app on its X1 set-tops. Still, the number one ranking is good news for Comcast, which ranked just fourth on the list in November.
