ELi5: When a server is taken down for routine “scheduled maintenance”, what is typically being done to the servers while they cannot be accessed?
In: Technology
Depends, but the term encompasses everything from updating software, installing security patches, upgrading hardware, migrating data, etc. Truly routine maintenance on mission-critical servers would include thorough diagnostic checks to uncover and thwart potential problems before they become actual problems.
In short, could literally be as simple as “turning it off and turning it on again” to “running full backups + swapping out hardware + updating or swapping out software + reinstalling data + thorough testing.”
