Joking aside, is there a famously _bad_ video or audio site, one that
everyone hates?
Or a setting for a service that makes it fail?
Here's an idea - no clue if it's a good one.
Get yourself access to a low bandwidth connection: if the following
table is correct (dubious source and video compression always varies
depending on content) then you can easily saturate a 10Mbps DSL line
with a 4K video:
Resolutions Required Bandwidth Required
H264 H265
1280×720(HD) 3Mbps 1.5Mbps
1920X1080(FHD) 6Mbps 3Mbps
3840×2160 (UHD) 25Mbps 12Mbps
4096×2160 (4K) 32Mbps 15Mbps
(source: https://www.synopi.com/bandwidth-required-for-hd-fhd-4k-video/
in case the table got mangled into unreadability. )
Maybe you have a way to fractionalize your own network connection if
you don't have access to 10/1 DSL.
With YouTube, you can select the resolution (although it's not very
granular at the top end). If you can toggle CAKE on/off, see if the
saturated line becomes unsaturated. If not, reduce the video
resolution and repeat. YouTube's "Stats for Nerds" may also be
helpful?
Aha, their stats aren't something I've looked into. Thanks!
