Looks like the problem trying to download updates from Apple is back and it's Telus specific again. Hovers around 30k/s on iOS and OSX . Switched to Shaw Open, since there's one nearby, and the downloads were noticeably faster though will take some time to complete.
It did the exact same thing the last time Apple released a new version of OSX.
Update: My brother has a developer account with Apple and downloading the OSX update there was 8MB/s on a Telus connection. The problem appears to be between Telus and at least one of Apple's software update servers.
I'm having an issue with OS X update downloads but also with Apple Music songs and videos. Videos won't play at all and songs continually cutting out.
I signed up for a VPN service (vypervpn has a free trial) and everything is perfectly fine. The El Capitan update that I started last night and still had 16 hours remaining when I got home this evening finished in an hour and a half once I connected to the VPN. Apple Music songs and videos stream just fine on it too.
There is ample evidence to support the theory that it is a Telus issue. Those of us that have access to a non Telus network have no issues once off of Telus.
If Apple servers are the root of the problem how were you able to grab it in 20 minutes?
I'm having the issue too. I'm trying to download app updates (already managed El Capitan) and it's painful. I heard Apple started using their own content delivery network; wonder if that's been overwhelmed through specific ports that Telus happens to connect to. Even though it's only affecting Telus customers, it wouldn't make sense for it to happen because of Telus. If that was the case, there would be service issues on other websites. The only way I could see this making sense is if Telus was intentionally throttling Apple downloads, but there's no reason for them to do that.
For me it's affecting everything, I can't even use my AppleTV to stream movies I've purchased from iTunes. However Netflix from the same AppleTV device works just fine.
Again though, as soon as I connect to a VPN everything is fine. I suspect you may be right about the port issue... or Telus really is throttling traffic to Apple servers but I highly doubt that, it would be a horrible business decision.
I doubt you will. The issue is far above tech support's reach. I've got ideas what it is but I'm not sure if it's on Telus' end or Apple's content distribution network assigning overloaded servers to Telus users trying to get updates.
@SalBala - is that Chinese DNS server safe to use?
