Any chance I can get someone with a Smokeping instance to add a host and monitor it for 10 days or so?

I've been listening to a streaming radio station in the UK for the last couple of years without issue but in the last month it's become unusable. The packet loss to this one specific host seems to be my issue but it would be great to have it confirmed.

My Smokeping target entry is...

++ TMM
menu = The Music Machine
title = TMM Radio | msmn3.co
host = msmn3.co

The actual steam is https://msmn3.co/proxy/x1mp31/stream

I contacted them directly but they are unaware of any issues their end but other hosts they own / run appear to work fine such as https://msmn8.co/proxy/cx128mp3/stream

Any assistance greatly appreciated.

Cheers, Tim

Out of interest, I ran an MTR for a 100 pings...

Seems to be loss gets introduced into the path around hop #13 once traffic enters the retn.net network.
Unfortunately this isn't a direct upstream of Quic/Vetta so hands are somewhat tied to a degree, depending on how the route is presented to us. It may be possible we to traffic engineer around it depending on what BGP communities we could get our hands on, and what alternative paths are available, but will need to discuss with our network guys.

Worth noting it's routing via Hong Kong -> Europe based on that trace, and there's significant disruption to traffic on that route as multiple cables have been damaged by Houthi rebels.

Interesting. It feels like it's been going on for longer than this but I could be wrong.

Also that it comes and goes with long periods like today where it was perfect.

Thanks for investigating; it's a small thing, but because I have it running most days it's quite a big thing for me. So I'd be most appreciative if you managed to make any difference.

I have had a bit of a look for you, and my poke around does hint to add weight to what @Lias has mentioned above.

There are a significant number of submarine cables cut currently between Asia and Europe. With this happening, carriers and providers are being forced to use paths with less capacity, or temporary measures in order to keep packets flowing, which causes congestion on the remaining paths that are working - but hey, moving most packets is better than no packets!

Fixing these cables is proving especially challenging, moreso than normal due to the instability in the region, needing military escorts and defense etc.

Doing some digging, it does look like RETN and/or their provider are striking this problem, which matches both in terms of the traffic path, and explains differences in time of day based on when the working path they're using is congested.

We have already completed some traffic engineering changes a month or so ago in order to route around points of significant congestion due to all the above with the elements we have control over, however we can't fix every path to everywhere, as we can't control the whole path to the remote destination.
