  "message": "Add two histograms for new connection on alternate network.\n\n- Net.QuicStreamFactory.AttemptMigrationBeforeHandshake.FailedConnectionType\ntracks the connection type of the default network when the original\nconnection fails with handshake not confirmed.\n- Net.QuicStreamFactory.MigrationBeforeHandshake.NewConnectionType\ntracks the connection type of the altenate network when the original\nconnection fails with handshake not confirmed and a new connection is\nabout to be retried on the alternate network.\n\nThese histograms may give us hints why the altenate network is not\navailabe when the connection on the default network fails. Current\ntheory is that the default network is on Cellular, and there is no\nalternate network.\n\nBug: 790547\nChange-Id: Ibfd63efed9a1b72b7d6de95453af55feacd9cef6\nReviewed-on: https://chromium-review.googlesource.com/c/1354320\nReviewed-by: Ryan Hamilton \u003crch@chromium.org\u003e\nReviewed-by: Alexei Svitkine \u003casvitkine@chromium.org\u003e\nCommit-Queue: Zhongyi Shi \u003czhongyi@chromium.org\u003e\nCr-Commit-Position: refs/heads/master@{#612414}",
