I am noticing strong signs of a similar problem that happened about a month ago in the area (North Langley). Internet performance is down: very bad pings, very bad upload speeds. It comes and goes for the last few hours. The symptoms are exactly the same as in the previous event, and the source of the problem at that time was noise being introduced by "that other company" into the Shaw network.
I just want to make sure that your network people are aware of the issues, and if possible if they are working on it.
P.D.: testing with DSLReports
