I have also had slower News Servers and general M-Web service the past say 2 weeks.
This happened before... wasn't it in Jan or Feb? Anyways... it did sort itself out and lasted until now.
e.g I have nothing running on my line and really struggling to load a good few YouTube videos (360p) and News Servers are 10kb per second.
I have a 1Mbps line. I am watching some vsauce now on YouTube and that channel seems to always work alright.. 360p. Really does seem like it's certain YouTube videos or certain servers that data is being pulled from.
