Launchpad itself

Our server's IP is blacklisted from launchpad.net

Asked by Martin Konecny

I tried asking on IRC #launchpad but no luck -

Adding a PPA (sudo apt-add-repository package) on one of our servers blocks for a few minutes and eventually fails.

I've tracked it down to our server not being able to contact launchpad.net at all.

For example, I can run "telnet launchpad.net 80" or "curl https://launchpad.net" from any machine except from our server. We are a 2 year old startup running on AWS servers and have never DDOS'ed the site.

I've tried to manually add the GPG key using

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys

But our server appears blocked from keyserver.ubuntu.com as well!

Here is the traceroute info:

If there is some private email I can send our IP address to, please let me know.

As far as our sysadmins can tell, there are no blocks in place that should affect your IP address. I think you'll need to investigate other things along the relevant network path; perhaps there is some routing bug between you and us.

If you need further assistance on IRC, it would be best to cut out the intermediate step and ask on #canonical-sysadmin; Launchpad staff don't have direct access to investigate firewall problems, and the best we can do is talk to sysadmins on your behalf.

Response from our sysadmins:

"nothing we're doing. it looks to be (quite) farther up. if I had to guess, I would say routing misconfiguration of some sort on the amazon side of datahop/6dg's peer"

We restarted our production server, and the problem went away. Thank you for your guidance.
