I usually use my phone with WiFi off or set up my phone as a hotspot while not connected to WiFi so my laptop can connect through my cell carrier's network. Always helps for testing external connections quickly and easily.

@LifeInMultipleChoice I tested a couple different things:1) General responsiveness: Not snappy, but fine. I am guessing this server is run on HDDs rather than SSDs. I always assume media on HDDs, but the platform itself had some notable delays. 2) Transcoding: Failed. I tested the newest Avatar movie (16Mbps to 10Mbps) and the server was unable to maintain live streaming. The video would stop to buffer regularly. 3) HDR: Couldn’t find any HDR content to test. 4) Intro skip accuracy: Seemed fine for the shows tested. I didn’t see my stress tester, Grimm. 5) Library organization: I know you asked for testing not reviewing, but I noticed a lot of content out of place. Season folders in the TV root directory, Jujutsu Kaisen’s season 1 is off the rails, etc. Within reasonable circumstances and expectations, everything was working. Was there anything specific that you wanted to check?

Pinged.

I can test from France in 3 hours if you want.

FTR: fiber connection, 160 Mbps download with a VPN in Sweden (Mullvad fuck yeah), same upload speed.

I lost a 2tb drive and had issues with the server recently, just switched to a new ISP so I figured I'd test.

You can limit your speed in the dev console of most browsers
