 Vladimír Čunát | Yes, this one but on a different derivation, apparently. | 13:43:21 |

| @drupol:matrix.org | Hey, do you have any idea why cache.nixos.org could be extremely slow at work? I contacted the helpdesk, and they confirmed there are no restrictions on their side... they suggested the issue might be external. The behaviour is strange: downloading just 30 MB takes around 15 minutes. It seems to follow a repeating pattern: the connection works normally for 1–2 seconds, then pauses for about 30 seconds, and this cycle continues indefinitely until the end. Nix is barely usable here :( Any idea how I could further investigate or troubleshoot this? Thanks! | 12:39:15 |
| @drupol:matrix.org | (feel free to redirect me to the right channel for this) | 12:46:09 |
| @drupol:matrix.org | Here's the traceroute session: https://gist.github.com/drupol/3825ac49a93c1f2d04c91286edf8e19a | 12:58:33 |
| @drupol:matrix.org | And a mtr session | 13:00:21 |

| @drupol:matrix.org | 20% loss somewhere... that's weird. | 13:00:30 |
 hexa | intermediate losses at routers is normal | 13:00:54 |
| @drupol:matrix.org | 27% now :S | 13:01:10 |
| hexa | the traceroute not completing could be a red flag | 13:01:14 |
| @drupol:matrix.org | Ok... | 13:01:14 |
| @drupol:matrix.org | yeah that's so weird :( | 13:01:35 |
| @drupol:matrix.org | I have that thing running for now 30 minutes: | 13:02:01 |
| @drupol:matrix.org |

| @drupol:matrix.org | Kinda frustrating. | 13:02:10 |
| @drupol:matrix.org | They do everything to keep their workers at home :D | 13:02:18 |
| hexa | also a very funny route | 13:03:05 |
| hexa | given that you are presumably sitting in brussels, but handing of the traffic to british telecom | 13:03:16 |
| hexa | for a detour via londoin | 13:03:20 |
| hexa | * for a detour via london | 13:03:22 |
| hexa | only to go back to amsterdam | 13:03:34 |
| @drupol:matrix.org | yes indeed, sitting in brussels at the moment | 13:03:39 |
| hexa | * given that you are presumably sitting in brussels, but handing off the traffic to british telecom | 13:03:53 |
| @drupol:matrix.org | Is there anything else I could do to try to spot where the issue comes from? | 13:04:00 |
| hexa | this really looks like the reverse path from fastly to your AS is broken | 13:04:16 |
| hexa | the solution is … peer with fastly somewhere and cut out the middleman | 13:04:42 |
| @drupol:matrix.org | What worries me is this: the behaviour is strange: downloading just 30 MB takes around 15 minutes. It seems to follow a repeating pattern: the connection works normally for 1–2 seconds, then pauses for about 30 seconds, and this cycle continues indefinitely until the end. | 13:04:52 |
| hexa | yeah, a route can flap | 13:05:15 |
