Some websites not loading or timing out

[wjtqc]

I have a quick question I was hoping other Sky users could comment on. Some websites are not loading. Firefox is giving the error: "The connection has timed out"

However, if I remotely log in to my computer at work the webpages load just fine. And if I wifi-tether my laptop to use my Android tablet on T-Mobile they work just fine. So as far as I can tell, there this is a problem specific to Sky Broadband (and I have unplugged the router) and not my laptop.

Can anyone else access the following websites from their Sky Broadband connection?
http://www.miktex.org
http://www.three.com.hk
http://help.thetrainline.com

If I try to "ping google.com" the replies are fast. If I try to "ping miktex.org" the requests all time out. Note that the IP address is being resolved to 46.163.68.162 so the problem is not the DNS server. (And the ping works correctly from http://network-tools.com/default.asp...ost=miktex.org)

Any ideas why these would time out with Sky but not with my work or T-mobile connections?

Thanks,
Ken

The first and last load for me in under a second, the Hong Kong one a bit longer, maybe a full second.

Regards the Ping, not all addresses are pingable, some choose not to be. However I am getting a response from miktex.org

Using Win7 and FF 7.

I am also having problems today with sites not loading or graphics missing. Oh and the sites you put up wont load for me either.

I wonder if you are in an area which is experiencing exchange problems, there are a few including Halifax and Coventry areas, maybe more.

How do I find out?

For the interested network-types amongst you (and anyone from Sky/Easynet who might be reading!) I think the issue might be Easynet's peering with Telia. Traceroutes to 94.0.0.0/12 from Telia's Paris Looking Glass don't get on to the Easynet network, but traceroutes to 87.80.0.0/13 do.

94.0.0.0/12 - Sky Broadband "Overlay" - people's routers (AS5607)
87.80.0.0/13 - EasyNet/Sky Exchanges - Easynet LLU equipment (AS4589)

My router is in 94.0.0.0/12 and traceroutes from Telia fail like so;

traceroute to 94.X.Y.Z (94.X.Y.X), 30 hops max, 40 byte packets
1 prs-bb2-link.telia.net (80.91.251.115) 0.442 ms 33.626 ms prs-bb1-link.telia.net (80.91.251.113) 38.158 ms

My first hop after my router (ADSL gear in my local exchange) is in 87.80.0.0/13 and traceroutes definitely show traffic getting onto the Easynet network;

Traceroutes from other ISPs that don't touch Telia get all the way to my router with no issues. Traceroutes out from me break either here;

te0-1-0-5.er10.thlon.ov.easynet.net

or here;

ldn-bb1-link.telia.net

The first one is a router inside Easynet's network, probably at TeleHouse in London (where they have their LINX peering) and the second looks like one of TeliaSonera's peering routers in London. TeliaSonera and Easynet both peer in Telehouse Docklands North and Telehouse Docklands East.

I also tested various sites from my office (using Easynet Business) and can reach all these sites fine, but the routes are flapping constantly between Level3 and Telia.

I'd phone and tell Easynet's NOC myself, but I doubt they'd talk to me Hopefully the guy from Sky will escalate it and it'll get fixed. It might not even be what I think it is, but I reckon that's where I'd start.

Plus doing all this investigation has distracted me from the fact I've not been able to play World of Warcraft for two straight nights now!

IBM loaded for me. The second link times out.

How do I find out?

I called Sky twice but they simply wanted me to try disabling my firewall, reset browser, etc.

However, the problem is experienced on both my WindowsXP and Linux machines and on the latter I have tried using a simple terminal browser. The sites still don't load.

But when I SSH into a remote server on a very different network, the sites load with a terminal browser.

So there is not much I can do since Sky's Broadband Tech Support won't do any more than try to reset my IE or Firefox browsers which is clearly not the issue.

I can only hope that one of the more experienced Tech Support guys will have a read of this thread and follow up if other users are reporting similar problems.

Now I am trying to check out via Amazon.com and no images are loading...makes checking out very difficult!

[Bordersquirrel]

I was still seeing these problems this morning, some pages have long loading times because ads, images or javascript pulled from other sites aren't working. Oddly enough Sky.com had this problem for me while I was talking to Sky Broadband customer support!

It definitely seems to be a routing issue, so I doubt that there's anything that the Sky Broadband support guys could actually do, short of escalate it to their core network team (which is what the 2nd-line guy I spoke to last night said he was going to do).

I think there is actually a real problem affecting users on Sky broadband here, but it doesn't seem to be everyone. If anyone who reads this could run a traceroute to eu.battle.net (one site I happen to know is still broken) and post it on here, it would be appreciated.

From an Easynet Business connection (for reference);
