why the renewal of certs often fail even for big tech companies?
My recent thoughts about cert monitoring and how you establish a strict monitoring regime:
Well we both are small companies with direct interactions and short processes. Try to imagine how this works in bigger ones, where a web developer puts something on any sever without telling anything to his IT department. Or when you are responsible for Ops for a company with a lot brands and websites, all managed by 3rd party Advertising-Companies and so forth many providers and on external servers.
The magic is the git repository and the distributed configs, not monit
I wouldn’t blindly trust 3rd party. I rather rely on my own established instruments and would use any 3rd party instruments only as additional confirmation.
