Terrible speeds from download.microsoft.com

[JamesR]

It has only come to my attention this afternoon that any download from download.microsoft.com is terribly slow, when usually they are quite fast (I'm assuming because they are fed from Akamai).

Is anyone else having these troubles?

Hmm... I wonder what it could be then.

Here is a ping and traceroute to download.microsoft.com if it helps:

My download at near max line speed was not encumbered by a filter. It's a safe site, so what happens if you disable malware filtering? (My traceroute gets ave 31 ms, by a different route)

I've just fired up the Ubuntu VM to see what the results from wget were... here's what it showed.

Mmm - resolved to 70.37.159.133 MS-GLOBAL-ONLINE-SERVICES So does wget for me now - 70.37.159.220 - still getting 800+ kB/s
Edit: can you get a better speed using multiple connections in axel?

Obviously faster using 20 connections, but that still doesn't explain why it is slow - it's normally super fast using Akamai, but since I've downloaded last from MS, it seems to have really died somehow.

Edit: Something has definitely changed... it's downloading much faster now using Firefox on Windows...

And again now at around 2.30pm it is extremely slow download, from another computer...

I downloaded 235Mb from MS site on Monday in roughly 7 minutes (no stop watch), during off peak, agout 10am.

Used the Microsoft download manager.

Will try additional tomorrow with more accuracy.
