How to find 'profile' speed now https://speedtest.btwholesale.com/ unavailable

[#1]

The pinned topics here cover FTTP and ADSL, Seems ADSL also means VDSL/FTTC?

The links to btwholesale speed-testing don't work for me, they hang forever.

I would like to see what my 'profile' speed is before contacting the helpdesk.

Over a long period (2+ years) my connect speed has dropped and dropped, in a step-like way, a few Mbs a step, from ~ 72 Mbps to average 38 Mbps. My Plusnet Hub2 currently today reporting:

Data rate:14.997 Mbps / 43.998 Mbps
Maximum data rate:17.740 Mbps / 62.774 Mbps
Noise margin:6.8 / 11.3
Line attenuation:8.6 / 17.9
Signal attenuation:8.6 / 20.0

How can I find what my profile speed is set to?

Thanks

P.S. Just got:

Broadband Speed Test

The BT Wholesale Broadband Performance Tester is no longer in operation.

@markv Looks to me like you  have a 'niggly' issue here. Your current upload/download speeds appear to be capped - with your attenuation figures and noise margin, I would expect you to be getting ~70 down/18 up.

@jab1 Many thanks for your opinion. I'll contact the helpdesk.
