Attempts to connect to server/humans.txt

EoL's ... 'end of life' for operating systems.
Am trying to keep ahead of the curve ... proactive rather than reactive ...
so this weekend am upgrading servers running CentOS 6 to CentOS 7.
Now if users here in community are on shared hosting, would think provider will eventually have to inform users of an upgrade - I would hope!
Managed hosting ... ditto ...
but un-managed and a rookie at it ... off the radar screen.
It could be possible to run PHP/MySQL/MariaDB/other that is currently secure and beyond 'end of life' of the operating system which isn't a good thing. The 'hole' may not be code but underneath the 'hood'!
