After adding an ARP mechanism to libp2p with the release of 2020.01.05.0 on January 6, 2020 we
noticed that gossip quality began to degrade again over time. To remedy this we decreased the ARP's
peer staleness time from 24 hours down to 6 minutes and began throttling ARP requests. We also
bumped the assumed valid block to 165,353 for faster resync times.

Deployment Plan
We plan to beta 2020.01.07.0 for a couple of hours starting at 1:45 PM PDT and confirm that the GA
release OTA downgrades successfully before making it available to all hotspots.
