DB settings failed

Scrapbox was inaccessible for an hour. We apologize for the inconvenience.

What happened

We deployed two at the same time.

• Code for new features
• DB index creation code for use in new features

A large number of processes requiring a non-existent DB index were running, and the DB hung up.

Remediation plan

Deploy the code that creates the DB index first.
Then deploy the new functionality.
