  To avoid sending requests to the Sentry API during periods of failure, we use
  a circuit breaker to update and check the health of the API. Currently, the
  fuse is configured to melt if the API returns unsuccessful responses 5 times
  within 5 seconds.  Following a melt, the fuse will be reset and API attempts
  will be allowed again after a 30 second reset period.
