Miek Gieben bae9514e94 pkg/up: implement backoff (#2342) ... * pkg/up: implement backoff Every 2nd failure we double the interval until we hit 4 * interval. This to have some sort of backoff, esp when a large cluster of coredns shares an upstream (original intent of up package) they will hammer the upstream. This put some back pressure on that.
