How not to do updates of your wiki site
Posted by jpluimers on 2021/02/17
If your company manages your own infrastructure, be sure you have monitoring on all levels.
It saves you from customers discovering issues like this: [WayBack] Thread by @jpluimers: “The @EmbarcaderoTech docwiki is down due to an error in duobook2.[…]”:
The @EmbarcaderoTech docwiki is down due to an error in duobook2. URLs pointing to wiki content fail, no matter the product. Examples for Rio and XE2 grabbed from docwiki.embarcadero.com/Libraries/Rio/… and docwiki.embarcadero.com/Libraries/XE2/…
This is the #1 reason for allowing archival of all your product documentation web-content in the @internetarchive, even for non-current products, as now only parts that have been allowed to save in the past are available.Apart from nobody noticing the outage yet, which is bad in it’s own way, I hope the cause is not somebody fiddling with duobook (3 year old and unmaintained) without testing the consequences. As that would make the cause of the outage embarrassing.

Finally it is rather odd to get a HTTP 200 SUCCESS code on a failure. A HTTP 500 or 503 would be far more appropriate.
I wonder if that is a @mediawiki thing; maybe they could shed some light on that.

The cool thing is that the stack traces teach you a lot about how a framework is structured.
