Well
that depends if they're using it to carry VM broadband traffic

There are only about 25 100GbE ports lit on LINX. Akamai alone have 6 of them, Apple have 2, Facebook have 2, Microsoft 2.
ISP-wise BT have 2, Sky have 3, TalkTalk have none: they use 32 x 10Gb.

That's true, but VM also have several times higher average speeds than Sky and BT, and BT for that matter have had 100Gb LINX ports since at least 2011. EE also have two. Basically everyone bigger than VM has multiple, despite VM having higher average usage per customer.

VM use 23 x 10Gb on the London LANs. Their network pushes >4Tb/s at peak so they must have a ton of other public exchanges, private peering and transit taking the strain.

Unfortunately I see that as part of the problem, as it's much quicker to add public peering capacity than new private peerings when dealing with unexpected traffic increases.
