[Clusterusers] Thanks for fixing Fly!

[Bassam Kurdali]

Thanks Lee for running those commands on fly; you made tractor working
again!
Since you asked, fly has to network adaptors (eth1/eth2) and tractor is
on eth2. It seems like there's a bug that causes the inteface to stall,
so stopping it with ifdown and stuarting it back with ifup is a
temporary fix. Hopefully when Josiah gets back he can diagnose and fix
it permanently.
Thanks for letting us render again!
