Sky hub shows Internet as Amber light, both other lights green, fun checks for broadband states everything OK, but still got Amber light?
Not sure what test and checks you have tried so if you haven't done this yet then try running the line test here to see if any faults are found:

You can also run the test via the MySky app on a mobile data connection.
After this has finished and if it reports back all is good click on broadband to run an updated test. If you get amber or red please follow the on screen instructions.
If this is of no help give Sky a call to report it to them.
Run the test from your link and alls OK but still have the Amber light?
I'm having same but my voice light is orange too sky site says everything working... it definitely isn't! I'm supposed to be working
