Estimated Line Speed

[#1]

Just checking my connection details and my estimated line speed is saying "There's no speed estimate currently held on your account".
Anyone have any ideas why?
It was there the last time i looked.

I'm not sure why it disappeared either but it looks like its back now from what I can see?

[#3]

Yes, back now.
Thanks.

The estimate on my account also disappeared sometime over the last few weeks. Mine has not come back though.

Mine has been missing for months
