### Timeouts ([.kt][ConfigureTimeoutsKotlin], [.java][ConfigureTimeoutsJava])

Use timeouts to fail a call when its peer is unreachable. Network partitions can be due to client connectivity problems, server availability problems, or anything between. OkHttp supports connect, write, read, and full call timeouts.

### Other (Cleanup or Flake)

    is now a stable API and is no longer considered experimental. Some of the
    major improvements involve handling peer failure and many bug fixes. Please
