Upcoming brief downtime

We need to take an upcoming brief downtime as part of our continuing 100% focus on stability. This outage will address an issue where payouts cannot exceed 100m coins at once, because the database precision is too low.

We will expand the column in the payout table to allow payouts of up to 10^16 coins, which will lock the table, but it should only take 1-2 minutes.

The maintenance has been completed successfully.
