The best about V/M the speed stays the same no matter what time of day it is.
Mine don't. They are all over the place anything from 9 to 60 depending on the server. My nearest server (Norwich) is usually very slow around 12 -20, but if I select Basildon or Northampton I get much better speeds usually around 40 -50. I rarely get the 60 I pay for. Spent hours on the helpline but they couldn't improve it.
