Greetings. On Monday, I would like to distribute this message to the 7 largest affected non-English wikis, just in case the time-estimation of possibly noticeable affects is exceeded. That is: Swedish, French, Dutch, Russian, Italian, Spanish, Polish It can be translated at https://www.mediawiki.org/wiki/Wikimedia_Technical_Operations/ICU_announceme... The smaller wikis are unlikely to notice the brief mis-sorting.
That page is also where the Tech/News item links to for further details.
Thank you for your help. :-)
