Microsoft's CDNs are painfully slow again

AshleyYoungblood · Dec 1, 2015

Is there an update on when Xbox Live's download speeds are likely to have a more robust collection of CDNs for those of us that can achieve 15+ MBps? I'd love to go all digital but XBLs downstream is killing me.

again slow downloads from Xbox Live

Xbox Live download were never fast for me - since the Xbox 360 (live in Germany, 200 Mbit Connection, Gigabit Router, wired connection), rarely I get up to 80 Mbit but mostly it's about 25 Mbit - now it's down to 2-4 Mbit. Since Xbox One still has no auto
update function I can't play any of my older games because every one of them needs an update. My Borderlands TPS is updating since one hour...

Every other Game CDN like Steam, Uplay, GOG and Browser downloads have up to 200 Mbit, can someone from Microsoft says something about this?

CDN stands for Content Delivery Network. It is what big web services use to get their content to you. Basically a whole bunch of servers.

Which would make it seem it is an issue on Microsoft's side. Literally the error says something is missing on Microsoft's servers. But because not everyone is experiencing the error it is hard to say what is causing it.

it worked for me the last 9 days, today cdn error again . it was stuck at the loading screen and downloading something. after 10-15 min i got the cdn error. does someone know what the app is actually downloding at the beginning? this happened to me a lot
of times even before the cdn problem

No, come on guys, Microsoft uses a CDN to deliver this stuff and it’s in their best interest to let it rip as fast as it can possibly download. That way the customer is happier and the transfer is done sooner, allowing more customers to start downloads. Downloads on Xbox are max speed and not throttled, which shows their intent.

This is almost certainly a TCP tuning issue in Windows that isn’t getting to the right people in Microsoft to fix.

I don’t know why Microsoft isn’t fixing this. It’s in their best interest to make downloads as fast as they can be. On Xbox, the same titles download for me at 600+ Mbps. On PC: 15 Mbps if I’m lucky. On the same connection. I assume that the CDN is the same for both, so I can only chalk this up to very poor Windows native TCP settings - unless Microsoft is trying to throttle these.

Same error here, "Resource not found. CDN error." when trying to launch Xbox Fitness. It had worked fine for me for about 3 weeks (sometimes it was really slow to load). It last worked on Saturday May 16, 2015, then yesterday morning, Monday May 19, 2015,
I started getting the CDN error and it has been the same since.

Can some one from support at least respond with what CDN stands for?

I'm not sure if I'll embark on the delete, reset, and reinstall route. It seems more likely to not work than work.

Please help us, Xbox support team!

The speed you get running the detailed diagnostics always connects to a server in Seattle no matter where you are in the word. It is not determined by DNS.

The store downloads and updates all come from various content delivery network(CDN) servers around the world.

The CDN you connect to is determined by your DNS.

You can determine your actual download speed by checking the bandwidth usage in the network app. There is a stat for current usage. Just check current usage while something is downloading. If the speed is a lot lower than the speed listed in the detailed
network stats then you are connected to a slow CDN and may benefit from changing DNS.

If both stats are about the same the there will be no need to change DNS.
