Subject: remove "announcement_distinct_hosts" from introweb JSON
X-Git-Url: https://git.rkrishnan.org/pf/content/en/footer/running.html?a=commitdiff_plain;h=8f0c417910ac5eb0a3b8cde1fa11d571755dbf06;p=tahoe-lafs%2Ftahoe-lafs.git

remove "announcement_distinct_hosts" from introweb JSON

The machine-parseable JSON output for the introducer status web page
used to include a key named "announcement_distinct_hosts", which counted
the number of distinct IP addresses advertised by all connected storage
servers. This hasn't worked since Aug-2014 when foolscap-0.6.5 change
the internal hints format.

This removes that field.
