From my mailbag:
I turn off the PC at home or the office once in a while. Now, I've server at colocation center. Do we need to run server 24/7? I do reboot the server once a month. Is it advisable to completely power off a server once in a while instead of 24/7 running?
Short answer - no.
A UNIX / Windows server should be online 24/7 to serve http requests, sale product and services or simply collect emails. Most servers are build to operate 24/7 for years. There is no need to power it off once in a while. You need to powerdown server only if:
- Hardware replacement (replace NIC or hard disk or power supply)
- Hardware upgrade (upgrade CPU or RAM)
