Enormous problems reaching xenforo.com

[BoostN]

I've had the same problem in the past.. it's been a few months now though.

There's not much we can do as the problem is between you and the XenForo server.

This is not exactly correct. Because the site visitor can never choose which route to the server he takes.

Xenforo.com is stored at a server computer in a data center which should be connected to the internet with 2 or more backbone access providers. If it is connected with only 1 backbone provider it would be a bad data center choice, so I assume those are 2 or more.

If one of those backbone providers has troubles, the routing protocol of the main backbone router of the data center usually finds a way to reroute the traffic to avoid them and announces that new route to all other routers in the world.

If the router is configured badly and continues to send some traffic over the problematic backbone provider, some visitors may see serious connection errors whereas other visitors can reach the site without any problems.

Note that this can even be done intentional by the data center owner, since unreliable backbone providers are much cheaper than reliable ones.

If you are a site owner who gets complaints about connections problems, you should not response with "not our fault" but contact your data center owner and ask him to solve the issue. If he can't and the location of the complaining visitors is important to you, you should think about changing the data center.

The above traceroute however looks fine to me. But the Softlayer (*.networklayer.com) backbone is known for being cheap and problematic. Just google for it. ;-)

Yesterday there were some major problems with fiber connections in Holland (http://tweakers.net/nieuws/97648/pr...jke-storing-glasvezelverbinding-update-2.html).
TS is from Belgium so I wouldn't be surprised if there is a connection ( )

 

[Robby]

Still having the same problems.
Can't even download new releases.

Try swapping your dns settings to opendns or googles dns. Doing so sometimes helps you to load sites that your ISP DNS is having problems loading.

And a new day on xenforo.
Really getting tired of this. Even can't contact support or nothing.

Have you contacted your ISP about this?
Have you changed your DNS as has been suggested?

Then you probably need to be looking at your ISP and flushing your DNS cache. Also check to make sure no browser add-ons are being used that might interfere.

What time was that attempt? I've been on and off most of the night here and haven't noticed any problems for me.

 

[whynot]

Can somebody help with this?
Check my username?
Can not even reach homepage for contacting support. Getting this:

Try this link: http://anonymouse.org/cgi-bin/anon-www.cgi/http://xenforo.com

What's the result?

If this happens on my site my hosting people would talk to networklayer.com's people.

 

[Deriel]

Everything in this thread points to a routing or network problem from the specific user (Robby) point, not from XF, so I doubt thet XF could do anything

I would try some of the tips from this thread: change DNS, try another rout (via proxie or VPN) and contact his ISP.

 

[Robby]

Changed DNS to googles and still same problem.

With this it works, strange

So why is it just with xenforo.com?

I'm also on Telenet (Belgium) and I don't have a problem.

@Robby are you messing around with ipv6 on your telenet connection?
If your settings are wrong you can have problems like this.

Nope just tried another ipv4 and opv6 adress in browser but that didn't help so.

What happens if you switch to Google Public DNS?
Do you still have the same problem?


https://developers.google.com/speed/public-dns/

The Google Public DNS IP addresses (IPv4) are as follows:

• 8.8.8.8
• 8.8.4.4

The Google Public DNS IPv6 addresses are as follows:

• 2001:4860:4860::8888
• 2001:4860:4860::8844

Yeah it's the same.
I have allready tried this with the manual from google.
Do you know how to get a new ip from telenet perhaps?

 

[Fred.]

Just switch your modem of overnight. If your lucky you will have a new IP the next morning.

If you use Google Public DNS you should see a traceroute like this.

DNS is unlikely to change anything. The IP resolved will be the same. The routing is down to where the packet starts from (and peering arrangements, etc).
