Instapaper, February 9
A file size limit for a MySQL database on Amazon's RDS service sparked an extended outage on the Pinterest property.
The online bookmarking site later reported that its engineers never even knew of the RDS limit of 2 TB for databases created before April 2014, and were given no warnings by the AWS service that the table storing its "bookmarks" was about to exceed it.
After being down for more than a day, Instapaper's service was revived with limited access to archived material while engineers worked to revive the rest of the database. Four days later Instapaper completed a full recovery.
