- Wikimedia Labs' HTTPS certificate
<https://en.wikipedia.org/wiki/en:HTTPS> expired for most of Tuesday 15
September. To reach Wikimedia Labs and Tool Labs securely you had to
ignore
your browser's security error message. There was no risk to data
security
during this time. [9] <https://phabricator.wikimedia.org/T112608>
Well, it would have been an ideal time to launch a MitM attack. It is
very very unlikely this happened (IMO), but certificate errors are not
without any security repercussions at all.
