Slow steam Downloads

dimko

Have you been wondering why steam is SOOOO SLOOOOW?


I caught SKY red-handed. They do traffic shaping based on DNS somehow.
Very likely other ISP's also do that.

Now there is very strong chance it affects other ISP's in Ireland.


Just I did not test those.


I suspect Steam is using something like peer to peer technology. And they(SKY) throttle it with DNS servers, not just that, but they specifically INTERCEPT your DNS if you are acting smart and using google's DNS or some other third party DNS.


So no, getting 8.8.8.8 is no longer a problem solver.

I suspect Virgin does same.

I have asked reps of SKY to comment on my bold claim. Lets see how they weasel themselves out. But people who will deal with it will not probably understand what's in the thread.
But lets wait and see.

You'll be waiting a while for that as you posted it in the wrong forum.

Of course they do packet shaping and throttling on services like Steam, they'd be mad not to. The new CoD game - that's about a hundred gigs of a download times thousands of customers = a disaster for their national network.

I switched to OpenDNS years ago when I was having such an awful time with Twitch streams on Virgin (they were still UPC at the time), never looked back.

Whats your definition of slow speeds?

I had a similar experience recently with Eir.

I was downloading COD WW2 last week. Typically my speeds are up to about 70MB/s but after I paused the COD download, I was only getting 4MB/s.

They seemed to throttle it depending on the time of day. At one stage I had 7GB left and the estimated time was 1 hour (at about 4pm). Roll on an hour when I checked it again and there was 20 hours left and still about 7GB left to download.

5mbit download on 75mbit connection.

And its reliably slow when I don't use my DNS.

Are you sure you are being throttled? 5mb/s on a 75mbit connection isn't awful when something like 8mb/s is the max you would ever get, is there some other element in play rather than it being a deliberate act.

I'm on Virgin and I get full speed, my parents have Sky and the few times I've used Steam when over for a bit the downloads speed were about what I would've expected. About 9-10mb/s on a 100mb connection.

dreamers75

Have Virgin and most I even gotten was 57mb on Origin. For a while (about a year) Steam would max at 10mb, now all of the 57 platforms I have average out at 30mb.

Im sure there is throttling and I would sadly agree with the ISPs if they do it.

there is difference between MBIT and Mbit. I always showed speed in Mbit.


But I will demonstrate it in a few minutes. I uploaded almost 4k video to youtube, i am waiting for it to be processed.

I know that but I assumed you meant 5mb/s on a 75mb advertised connection, which isn't crazy low or anything, though less than optimal. If you meant 5mbit speed on a 75mbit connection, that would literally mean 700kb/s which I doubt is happening.

Again I am on Virgin and I get 28mb/s on a 240mb advertised connection, which is pretty much full speed. I've never had sky but my parents have it, the odd time I've used it I would get about 9mb/s on a 100m connection which is also decent.

I have Steam, Battlenet and Origin and they all work at full speed on Virgin without any issues. There could be geographical restrictions in place maybe.

Long gone are the days of downloading Day of Defeat on 3kb/s, starting on Friday evening, leaving it connected overnight and getting up on Saturday morning.

That's interesting. I wonder if it's region based rather than a general thing? Next time I'm at my parents house I'll check their Sky again.

This might be of help:


https://docs.microsoft.com/en-us/powershell/module/dnsserver/test-dnsserverdnsseczonesetting?view=win10-ps


I did not try it, but from looks of it it will do DNSSEC resolution and validation.


And check it vs this:


https://dnssec-analyzer.verisignlabs.com/pir.org


I use DNSSEC protected domain pir.org to test my hypothesis.


Remeber, just using 8.8.8.8 for DNS resolution wont work, intercepted at ISP level.


I can work around it easily because I have my own DNS server that gets DNS data over secure privacy tunnel.

A few points:

CDNs commonly use DNS servers to determine location for rendezvous purposes. So using a DNS server unknown to the CDN involved will change the routing path compared to a well known DNS source like Google's.

Equally using a VPN also changes your routing path.

Valve use both their own CDN, and other third party ones, usually the three biggest ones, Akamai, CenturyLink and Limelight.

I'd be far more inclined to suspect a congested peering arrangement, a sadly common place thing, rather than some far more exotic cause like DNS interference.

please look at video I attached to my first message.


Its not congestion. I can trigger issue at will

Not really sure what your issue is tho? If an ISP throttles downloads its for the greater good whether you or I like that.

You can:

Workout the time it will take to download a game @5mb and live with it.
Switch ISPs
Use a different DNS

No it's not. I pay money for privilege of using connection. So no matter how I look at it - it's bad for me.

Yes, I can do many things.
Also I can make sure people know they pull that trick.
I am making community service here.

Does a VPN subvert the throttling?

Its not tho, its in your terms and conditions that you agreed to when you paid for the service.

Everyone knows every ISPs do it

First of all, I did not agree to ANY terms and conditions.
Second of all, companies do unreadable terms and conditions on purpose, that doesn't mean they should not get away with it.


Not everyone knows is. And not every ISP does it.

DNS in VPN subverts throttling.

If you signed a contract, then you agreed to their terms and conditions, there's no escaping that and trying to claim otherwise makes you look foolish and diminishes your argument. It's a business contract. You pay for a service and that service comes with terms and conditions. If you're not happy with them, you choose a different service provider. That's how capitalism works.

ISPs have to do this. ISPs have always done this to one extent or another - maybe not specifically with Steam in the past, but you can't expect there to be unfiltered and unmanaged traffic flying around an ISP's network, it'd kill it. Anyone with any Networking experience knows this is the case and anyone who sits down and thinks about it for 5 minutes will agree that it makes sense. Roads have speed limits, roundabouts, traffic lights, etc - all to control the flow and make transport work - why on earth would data transport be any different?

And... there is always something else.

I am USER of said network. I am not it's contract holder. Holder is Sky user for many years, so changing/cancelling contract for him is gonna be very easy. It gets better. I have opportunity to get other BB connection FREE OF CHARGE. My employer is happy to pay for it. One of my perks at work.


So they seek for my details and they won't talk to me, cause GDPR.

Oh Well, their loss. If other customers of theirs are affected by an issue, best of luck solving it, where there is silent failure at play. Instead of talking to somone who is up to date with technology, knows TCP/IP protocols fairly well and is willing to troubleshoot their issues. Assuming they are issues and not 'design feature and not a bug'.
