Static IP Address & Ping Question on FTTP

[#1]

Plusnet has upgraded my parents from SOGEA 80/20 to Full Fibre 160/30 successfully. But, I was surprised the static ip address remain the same on FTTP as it was before on SOGEA. I thought if you change to FTTP as part of upgraded from SOGEA, you will lose Static IP Address? 

Full Fibre speed test with 11ms ping: https://www.speedtest.net/result/a/11496090678 

I thought Full Fibre are very low ping? Why it still on 11ms as it was the same as before on SOGEA.

The static IP Address is accountname based NOT connection.

Was the speedtest from a wired device?

Maybe consider setting up a thinkbroadband BQM

@goldenfibre  Static IP address is linked to the user account so a change to FTTP  does not change the address
