KCOM service availability - high amount of "unknown" since mid-June?

[pete]

Looking on the KCOM portal > Performance, I see the attached (30days, 7 days, 24hrs). Is anyone else seeing these dips?

 

I'm aware it could be a simple case of "whatever's feeding data to those graphs can't keep up" or "someone's messing around with the monitoring", but given it's customer-facing monitoring I'd expect a "hey, we're messing about and it might look a bit odd" note on the portal if that were the case.

 

And the Internet has been non-specifically grindy at times unrelated to the little darling's escapades.
