Thanks for the info. I'm glad that all of the data will be recovered.

Forwarding news of data loss. :( Hopefully it
will all be recoverable.
Hello,
We believe no data has been lost - the data inserted during the incident is
still at our codfw DC (the active DC at the time), as there were no issues
on that process.
At first and to quickly mitigate the impact of this incident we re-filled
all the rows that were inserted using the binlogs from codfw for the most
important tables, which might have left inconsistencies but not empty rows.
At the same time, and in parallel, we are recloning eqiad DC hosts from
codfw hosts (which have all the data, as there were no issues there) so all
the data will be back in eqiad without inconsistencies as soon as we finish
the recloning.
Cheers
Manuel

Subject: [Wikidata] Data loss during the data centre switchover
To: Discussion list for the Wikidata project. <
wikidata(a)lists.wikimedia.org>
Hello all,
During the data centre switchover routine
<https://wikitech.wikimedia.org/wiki/Switch_Datacenter> on October 10th,
some unexpected problems occurred over the past days:
- For a few hours, a small part of the data was not accessible. Some
items and lexemes seemed to have disappeared.
- Some data may have been lost, including edits, preferences changed
as
well as user accounts created during a period
or about 50 minutes
(from
2018-09-13 09:08:17 UTC to 2018-09-13
09:58:26).
Part of the data has already been restored (edits and revisions. The rest
(user accounts, preferences) will be restored at the beginning of next
week.
If you edited Wikidata on September 13th, please check your
contributions.
If you encounter any problem in the next days,
like items not reappearing
or something missing, let me know.
If you're interested in technical details, you can have a look at the
Phabricator ticket <https://phabricator.wikimedia.org/T206743>. Thanks
for
your understanding,
