"""external_link.recoveries: how many times recovery has retried a dead link.

The daily recovery gives a dead link one more attempt, spaced further apart
each time, and leaves it dead once the count reaches its limit. A link that
can never succeed is then downloaded a handful of times in total, not every
day.
