3Gbps upload suddenly became less than 800Mbps

Just noticed the upload on my line became wonky and then flatlining at ~800Mbps since this morning, anyone else seeing the same?

It's done against ookla speed test, server is selected at random at the time of test, from the list of speed test results I can see Community Fibre, YouFibre, No One Internet being used frequently. All of them are giving me a consistently slower speed of ~800Mbps upload.

For completeness these tests are done automatically with this: https://github.com/alexjustesen/speedtest-tracker

I've been getting consistent 3Gbps up/down speed until this morning.

After some troubleshooting the fault appears to be with the Adtran ONT, which I managed to clear with a turning-it-off-and-on.

Before the reboot I tried connecting my laptop directly with a 10GbE adapter to the Adtran ONT, the speedtest there was also faulty - 3Gbps down, around 1Gbps up consistent.

As a last ditch attempt to troubleshoot this, I unplugged the power to the Adtran ONT and plugged it back in.
To my surprise, as soon as it came back up, my internet speed was back to 3Gbps/3Gbps. I then swapped the connection back to my router (CCR2004), and all was back to the original 3Gbps/3Gbps speed.

No idea if someone was toying with connection profiles and left my ONT using the wrong speed, but this wasn't great since I would have no way of resetting it if I'm away from home.

I've raised a ticket with CFL (R-186643412) hopefully someone from CFL will know enough to pull some logs and see what happened there.
 
Not many logs on the ONT to read from. See if they do you a favour by trying to get an RCA. Restarting the ONT is always a good way to roll in case of doubt.

Are you speed testing every 5 minutes or am I misreading the graph?

Yeah I hope they'll go through the trouble, but by my experience it is really down to the engineer that I got. Fingers crossed.

Every 3 minutes, overkill in most cases but I get more data points to work with.

i do every 2-3 hours, cant remember. with the docker tracker.

edit: smokeping is cool too. check it

Why... Just why? I understand more data points but it's very unnecessary for residential and a much waste of bandwidth :rolleyes:
Like not saying not to do it but even once an hour would give you enough and that's still overkill

Would you do the same on something like the 8 Gbps product I have?
 
its probably a software he got himself,
