Problems that come and go.
WHAT INTERMITTENT USUALLY MEANS
A resource limit being hit at busy moments.
The site works when load is low and fails when it is not.
WHAT ERRORS INDICATE IT
508 resource limit reached 503 service unavailable Connection errors Very slow responses followed by normal ones
WHAT TO CHECK
Resource usage graphs, at the time of the failures Whether the failures correlate with traffic Whether they correlate with scheduled jobs
THE CRON CORRELATION
Failures at regular intervals frequently align with a scheduled job.
Compare the times.
THE BOT CORRELATION
Bot traffic arrives in bursts.
Raw access logs show requests by time.
WHAT TO FIX FIRST
Caching, in almost every case.
It reduces every resource simultaneously.
WHEN TO ASK US
If you have checked usage, enabled caching, and it persists.
Tell us what you found.
