i always found this to be upsetting as an IT tech at a former company - when a network or server had an issue and i was sent to resolve it, it was a "just reboot it" fix, which never kept the problem from recurring and bringing the server down at 07:00 the next Monday.
the limitations on the questions i could ask hurt that SLA more than any network switch's memory leak ever did, and i felt as if my expertise meant nothing as a result.
same, i've been very happy with Caddy, even with lots of subdomains and weird configs it's been rock solid.
