The [Wayback/Archive] Embarcadero/IDERA Documentation Wiki has been mostly down since March 3rd, 2022 (not the main page, but almost all other pages are).
I modified [Wayback/Archive] Docwiki https – EmbarcaderoMonitoring to show the actual status of a deeper page as the (mostly static) top page is up, so monitoring that is useless as the deeper pages are down.
The deeper pages are dynamic and require a functioning MySQL database connection. That connection is mostly down (the error message is not clear, so this could be a network or a database server problem, or maybe even a loadbalancer gradually entering bit heaven).
Since it had been down for like 6 days in February*, I’d expect Idera to keep an eye on it and prepare for more downtime. Apparently that’s either not a 24×7 thing for them or they missed the “pre” in preparation as it is dead-silent on .
It also runs on an unsupported version of Mediawiki 1.31** which by itself does not explain the outage, but does indicate that their idea if handling their internal lifetime management is different than what they advocate to clients in their software subscription model, see [Wayback/Archive] Delphi – Embarcadero store, [Wayback/Archive] Update Subscription – Embarcadero and [Wayback/Archive] Special Offers on RAD Studio, Delphi & C++Builder – Embarcadero:
Can I obtain updates and hotfixes without a subscription?
An active update subscription is the only way to obtain updates and hotfixes.
Back in the days Embarcadero were keen in advocating life cycle management. Maybe time to show they indeed still understand what that means.

The original 7 day outage from 20220217-20220224 was reported at [Wayback/Archive] docwiki.embarcadero.com is not working – General Help – Delphi-PRAXiS [en].
I amended some information at [Wayback/Archive] docwiki.embarcadero.com is not working – Page 2 – General Help – Delphi-PRAXiS [en] and redirected a [Wayback/Archive] UptimeRobot | Free Website Monitoring link at [Wayback/Archive] Docwiki https – EmbarcaderoMonitoring.
A few hours later it sort of looked to be operational again, but in the monitor actually showed it was having outages every few minutes for intervals of 5-45 minutes: [Wayback/Archive] Docwiki https – EmbarcaderoMonitoring.
**
The source of the docwiki home page at [Wayback] docwiki.embarcadero.com/ shows this:
<meta name="generator" content="MediaWiki 1.31.1">Mediawiki 1.31.1 is not even the most recent LTS version 1.31.16 (see [Wayback/Archive] Release notes/1.31 – MediaWiki), so here might even be CVE vulnerabilities.
When choosing for LTS, then they should go to the latest of 1.35 (at the time of writing 1.35.5), see [Wayback/Archive] Release notes/1.35 – MediaWiki.

Failing method is called by the class starting at [Wayback/Archive] …/mediawiki/blob/1.31.1/includes/cache/localisation/LCStoreDB.php – Line 28.
I have bolded the line numbers of the failurs.

Related class documentation (with diagrams how they related to the rest of the Mediawiki system) is at:
- [Wayback/Archive] MediaWiki: LCStoreDB Class Reference
- [Wayback/Archive] MediaWiki: Wikimedia\Rdbms\Database Class Reference
Based on these and some of the requests succeeding, there seemed to be three possibilities:
- Sometimes the load balancer cannot get a database connection at all
- Sometimes the load balancer gets a valid connection and that connection then fails returning a query
- Sometimes the load balancer gets a valid connection and that connection succeeds returning a query
But then [Wayback/Archive] Remy Lebeau (of Indy fame) kicked in with another backtrace at [Wayback/Archive] docwiki.embarcadero.com is not working – Page 3 – General Help – Delphi-PRAXiS [en]:
It is not just the load balancer that is having issues. For example, trying to access several pages today, I’m running into a new kind of error:

I only realised after searching for the table name [Wayback/Archive] lib_sydney_en_l10n_cache – Google Search that it was odd.
I could reproduce it as well at [Archive] Internal error – RAD Studio: XE8 main page:

Look at the table names:
lib_sydney_en_l10n_cacherad_xe8_en_l10n_cachecde_alexandria_en_l10n_cache
They have three different prefixes (lib, rad and cde) and three different product codes (sydney, xe8 and alexandria).
This looks like a a setup with each product version having at least three different Wikimedia databases each having an l10n_cache table. Searching for [Wayback/Archive] l10n_cache – Google Search resulted in [Wayback/Archive] Manual:l10n_cache table – MediaWiki (which describes the table for all ranges of Mediawiki versions) and a whole load of pages with various circumstances in which people bump into missing this table.
Then I looked into the current status monitor to see is anything substantial had changed since yesterday. And it did.
Current status
At [Wayback/Archive] Docwiki https – EmbarcaderoMonitoring – docwiki https it looks someone started working on it almost 15 hours ago:
Response Time Last 2 days
5012.65ms / 10372.00ms / 214.00ms

The reason is Internal Server Error.500Details:The server encountered an unexpected condition that prevented it from fulfilling the request.March 7, 2022, 17:57 GMT +00:00Running again

I really really hope they know what they are doing, as right now the databases don’t look well and things have not improved for more than 15 hours (I was interrupted while writing this reply).
Opinion
That their largest and most important site is still failing and there is no communication from Embarcadero on social media or 3rd party forums (they do not even have their own [Wayback/Archive] Embarcadero Discussion Forums and direct to 3rd parties at [Wayback/Archive] Community | Embarcadero RAD Studio, Delphi, & C++Builder Blogs) is inexcusable.
I searched social media. The only query returning anything useful was [Wayback/Archive] docwiki – Twitter Search / Twitter which only this Embarcadero response:
[Wayback/Archive] MarcoCantu on Twitter: “Yes, there is a technical issue with docwiki server our IT team is looking into” / Twitter (20220216)
