I just got this error (11:38) when trying to load https://nl.wiktionary.org/wiki/Overleg_gebruiker:Alexis_Jazz :

Onze excuses. Deze site ondervindt op het moment technische problemen.

Wacht een aantal minuten en probeer het daarna opnieuw.

(Kan geen toegang krijgen tot de database: Cannot access the database: No working replica DB server: Unknown error (10.64.0.97))

This is Dutch for "Our apologies. This site is experiencing technical difficulties. Wait a few minutes and try again. (Can't access the database:)

Immediately after I tried loading another page on nl.wiktionary which presented the same error. Directly after that I tried loading meta, enwiki and nlwiki which all worked fine. After that, I found nl.wiktionary was also working again.

I'm reporting this just in case. Maybe it's nothing.
