Double-check implementation for SRV disaster fallback values
We do have a check for our disaster_srv calculation (in tor_netdir::hsdir_params::test::disaster)
, and its value does seem to match up with the C tor implementation's test value in (test_hs_common.c:test_disaster_srv()
).
But we should create higher level disaster SRV tests, to make sure that we actually build the same ring that C tor does.
We suspect that this could be related to a bug encountered on a day with the authorities failed to negotiate an SRV (‽).
