Cannot apt update after linode forced migration

Aloha, all.ug

So all has been running fine with my VPS for as long as I've had it. Until recently.

Linode sent me emails about a scheduled migration. I had no idea what it was for, or why it was necessary, but I assumed it wouldn't be a problem. I just ignored the emails, and let it go through. Now, today, when I want to install some more packages, I find out that the linode mirrors that come preinstalled (I didn't ask for those, but whatever) are not responding. Doing 'sudo apt update' hangs at '0% [Connecting to mirrors.linode.com]…'

Maybe it's a problem with the linode mirrors? So I use the default for /etc/apt/sources.list with https://repogen.simplylinux.ch/. That also doesn't work. So now I try a simple test: lynx http://google.com … Nothing. That also hangs. So it's the VPS I guess. Somehow the network isn't configured properly. Now, I have played with the firewall (ufw) to allow through (in and out) some apps, but that was all working hunky dory before the migration. And even if I disable ufw, nothing changes. So I'm at a loss.

Oh, and weirdly… If I do 'lynx http://bing.com' it works as expected.

Any ideas on how I can debug this?

Cheers
