Great job upgrading to 2.2.3+ .. 27 nodes more to go

Great job everyone upgrading to 2.2.3 or 2.2.4!! 395 nodes upgraded.

Only highlighted 27 nodes are in version 1.x or below 2.2.3.
Btw, is anyone following up with them to upgrade?
Will it impede the network performance anyway, if unaddressed?

96% of the nodes are upgraded; 6% of the nodes' upgrade pending.
