 Picnoir | * Hey.
Substitution of big files is pretty slow today. The connection starts full speed but gets throttled to ~200kbps. It's not noticible on small files but very noticeable on big ones.
Is it a transit doing unhinged QoS between me and fastly (zayo -> LONAP IX) or did we change something in the fastly config?

 hexa | nothing in the fastly config on our end changes for a long while | 17:44:07 |
| hexa | well, that's a lie | 17:44:21 |
| Picnoir | wget https://cache.nixos.org/nar/1sjixbc2hfa2h8q5phbalqcrf648k7c46sv4gb2nii46hpg1w23n.nar.xz <= is a good test | 17:44:28 |

| Picnoir | Right, it's definitely on my side. Sorry for the false alarm. | 17:45:00 |

| hexa | we enabled h3 and tls1.3 recently | 17:46:40 |
| hexa | and switched to LE certificates | 17:46:47 |
| Picnoir | Today? | 17:46:56 |
| hexa | but nix isn't using h3 yet iirc | 17:46:57 |
| hexa | no, weeks ago | 17:47:01 |
| hexa | early december | 17:47:12 |
| Picnoir | Right, likely unrelated. It was working fine yesterday. | 17:47:18 |

Right, it's definitely on my side. Sorry for the false alarm.
It might be a problem specific to your region. If a prefix is fast and then it slows down a lot, it might be just filling from S3 to Fastly being slow for some reason (at that location).

 Julien | Hello hello | 20:27:24 |
| Julien | Would it cause any issue to the infra team if the nixos project took ownership of nixpkgs-update ? | 20:27:55 |
| Julien | If I understand correctly, short term that would involve just transfering the server(s) to our hetzner account | 20:28:44 |
| Julien | Maybe some context here: with potential unstability in the short-term future of nix-community, SC had been contacted to recommend nixpkgs-update migrates to the NixOS org. | 20:39:02 |
| hexa | https://github.com/orgs/nix-community/discussions/2132 is the related discussion at nix-community | 23:16:44 |
| hexa | We certainly need to make sure nix-update keeps working | 23:17:10 |
| hexa | There is no Haskell knowledge in the infra team from what I know. | 23:17:34 |
| hexa | But maintaining another machine should not be a problem | 23:18:28 |
