Issues this morning are settled but our team is still monitoring it actively. There was a disk issue related to capacity on one of our servers which caused a cascade of issues, while there was some activity on the Database that caused some major stress on MySQL. We have resolved the issue and found a permanent fix in place to prevent it from occurring in the future. If any of you see any additional issues on your sites, please contact the WP Engine Support Team as soon as possible. You can email us at firstname.lastname@example.org .
