“We’ve designed the Mailbox service to scale indefinitely, and have done as much load testing as we can. But we don’t know what we don’t know, so we’re using reservations to add people gradually.
At first, the pace may seem slow. This is by design. If we run into unexpected snags, we may even stop filling reservations temporarily. But as the service grows, we should be able to dramatically increase this pace until we no longer need a reservation system at all.”
- the on-boarding process for Mailbox is one part transparent messaging, two parts velvet rope and a dash of soup kitchen line.
