So the actual story behind this is that Rogers, the Canadian ISP, is accidentally throttling WoW players because they automatically throttle P2P traffic.  They're only supposed to be throttling file-sharing programs. 
 
Considering all the hubbub over the bandwidth limits in Canada, it seems like things just continue to get ridiculous with how things are going with their intrewebs.  
 
Reading through some of the comments, there are other customers who have had problems with programs that get recognized as P2P, such as Remote Desktop, or VOIP providers like Ventrilo or Teamspeak.
 
See here's the thing though.  It's not an accident.  Patching in WoW is P2P these days (unless you specify otherwise).  Not to mention there's background patching now too, so you don't just patch on patch day.  So no wonder they'd throttle it.

The Warcraft installer IS a P2P client, I think. It's like a torrent, they pull the data from people who already have the game installed, and send it to the people who are actively installing the game, so they don't have to have millions of people downloading 22gb game clients every day. At least, I think that's how it works. Anyway, I don't think they should be throttling regardless, but they're just doing what they said they were going to do.

Internet here in Canada SUCKS! I moved for Europe to Canada 2 years ago and it's really embarassing. I was looking into those Roku boxes  but many of the services that seem interesting (like MoG) don't work in Canada. The "fixed" bandwith issue is what gets me most though.
 
They really should get some competition going here regarding TV, internet and mobile because it's just pathetic.

I don't think anyone is surprised that a Canadian ISP was fucking over it's customers. I don't think anyone is surprised they didn't even know they were doing it. The Canadian Internet industry is a piece of shit and nothing they do should surprise anyone.

Even 3rd world countries have better internet than Canada, sadly this doesn't surprise me.

wow that sucks. they should give some people their money back or discount for a while for wow players. pretty stupid that they would do that.

There are some WoW players I'd like to throttle.

Sigh... I hate my country some times.

Blizzard's P2P downloaders use the full range of BitTorrent ports, the same ones ISPs want to filter due to their use by filesharing programs. I wonder if simply moving out of that port range (assuming it's technically feasible for them, I ain't no technomans) would solve the majority of the issues.

I guess that's the price you pay for having a functioning healthcare system...

How can you throttle WoW? Just playing+vent i used less than 50mb for an hours play its not exactly taxing is it.

Are bandwidth limits in effect here in Canada yet? I haven't noticed if they are.

Comcast has a limit of 250gigs a month.  They finally added a counter to their site.  My history:
 
Dec 158gigs, Jan 116gigs, Feb 69gigs, March 195gigs.
 
I've been watching MLB spring training on their streaming service every day and usually multiple games.  Most spring training games are in SD so when the season starts Thursday, I wonder what those HD streams are going to be like.
