Starting at 0:10 UTC on July 5th, the Wikimedia Foundation suffered from
intermittent, partial power failures in the internal power network of
one of its main data centers in Tampa, Florida. Due to the temporary
unavailability of several critical systems and the large impact on the
available systems capacity, all Wikimedia projects went down. The power
situation stabilized at 1:12 UTC, and systems and services recovery has
been taking place since. We expect all projects to be back online and
editable around 4:00 UTC.
