extras.ubuntu.com: one of two webservers not responding

Asked by dario

I had some problems with my updates recently, where sometimes the server at extras.ubuntu.com could not be reached.

Using 'host extras.ubuntu.com' I get back two possible IP Addresses:
extras.ubuntu.com has address 91.189.92.152
extras.ubuntu.com has address 91.189.88.33

Now '91.189.88.33' works just fine, but '91.189.92.152' does not respond. So, whenever my PC picks the .152 IP updateManager will fail (Mostly it simply doesn't start at all in that case).

Hope this is the right place to get this fixed... If not, I'd appreciate a hint where I should post this.

Any help?

thx

Dario, this issue happens all the time or sometime. Can you get back to us with some test results to the ip 91.189.92.152 when the issue happens again?

Do all this tests from the ubuntu box that's showing issues.

yup...thats wht the issue....from your box you are not able to connect to the 80 port of the that particular server ip. Can you check your outbound firewall settings if you have any?

Can you help with this problem?
