So, I wanted to search for stuff on https://git.launchpad.net/~ubuntu-kernel/ (via How to obtain kernel source for an Ubuntu release using Git) but all I ever get is:
503 Service Unavailable
No server is available to handle this request.
Tried from different networks, same result. I know about the recent DDOS attacks but the announcement has not been updated and the Status page states that everything is operational.
Does anybody know what’s up with the Git repos? Or am I looking for the wrong URL?
(PS: Oh, and snapcraft.io appears to be down as well, but that’s not part of the Canonical status page)
Yes, it’s showing 503 service unavailable. Sometimes. But it’s not really necessary to post about it. I’m sure Canonical’s IS is aware.
Nah, it’s all good. https://status.snapcraft.io
As someone put it in the Ubuntu Community Matrix room, status is hosted in a different reality. 
I, for one, fell victim to collateral damage from some DDoS mitigation, which prevented some people from connecting to this very Discourse instance over the weekend. I don’t think the posted workaround for that will help you but here goes:
sudo ip link set dev enp2s0 mtu 1320
(replace enp2s0 with your network device; see ip link if unsure)
Well, I hope they are aware, I wish the DDOS topic would get a few more updates, to prevent postings like mine :-\
Wrt. Snapcraft - it’s the same situation: the status page says it’s up, but their web page says:
We are currently experiencing service degradation and working on resolving this. Thank you for your patience and understanding.
Anyway, thanks for responding, I’ll just be patient then.
That…sounds more like a PMTUD issue on your end, no? Last time I had to adjust the MTU on my local link was…uh, back in the days when I attempted to get my new DSL connection going 
It’s what was posted to the Matrix room; I only copied it. I cannot even tell you if it worked, because I only noticed it after the issue was fixed.
FWIW, I am behind a cheap router from my ISP and have never seen anything other than MTU 1500 for my local link to said router. So, if anything, it’s an issue with how Ubuntu handles PMTUD. Or something in the chain was broken due to the fallout of the DDoS mitigation. I think those able to connect were on mobile clients, which usually have a direct link to the internet via LTE modems and the likes.
