Yup. At midnight on 2024-06-30 all CentOS 7 system will cease to function.
To avoid this, you will need to power them down before midnight, and when you turn them on in the morning, make sure to manually change the date.
[Yes, this was sarcasm/joke, like the Y2K bug was].
You have a couple options like @overseer mentioned.
ELevate to AlmaLinux 8 or extended support from TuxCare for CentOS 7.
With the far far away EOL for AlmaLinux 8, I personally think CWP is going to leapfrog 9.
But time will tell.
