Sorry to hear you’re challenged again, though good to see you went several weeks without problems. It can happen.
So please do clarify, though, what “happened”? For one thing, the subject of the thread is “service not available”, and that can display when for any of many reasons CF is not responding. What have you seen in the CF logs (not application.log, but ColdFusion-out.log)? Does it show CF going down? Coming up? Anything else in the log happening around and before the time of such a restart?
For another, you mentioned in your previous note an issue of “random app pool failings”, so it may be helpful to know if that is happening here (or not). Anything in the Windows event logs? As noted before, some such app pool failings were because of the need to rebuild the app pool after applying certain CF10 hotfixes, but I suspect you did that some time ago. Still the event log may give some additional insight.
Finally, there’s always the possibility that CF is “not responding” not because it crashed or has been brought down, but simply because it’s hung (still up, but just not responding). And for that situation, there may be no errors in any logs, but you may find with any of many tools that CF’s request threads are tied up with some long-running requests—and that could be just a random problem based on load or code, not an inherent deficiency in the stability of CF itself. Among the tools that can help are the new CF10 metrics.log, which tracks how many requests are running and have run. Then there’s the old school CFSTAT command-line tool. And of course the CF Server Monitor for those on CF Enterprise, and FusionReactor (and its useful new FREC logs) which can be used by someone even running CF Standard.
Hope some of that helps you or future readers.

Sad to report. Yesterday happened again. Almost month and a half.
