Last Thursday, our on-premises Confluence turned out to have died without announcement. No more responses, although the apache wrapper (local proxy) and also the shipped Tomcat itself still ran thoroughly. The log files, although excessively detailed, if not bloated (as with any contemporary Java application stack), did not tell too much, actually they said nothing that gave any hint.
For internal infrastructure tasks, we needed a simple, robust and reliable tool for dynamic DNS updates.
We were not aware of any DDNS provider completely meeting our requirements. Neither did various approaches out in the wild. Also we prefer processing sensitive data on premises anyway. In the end, I decided to refactor a set of legacy tools I once had quickly written (and which soon had become a “persistent interim” for some years).
