== Live Demo == 

[http://testgrid.allmydata.org:3567/uri/URI%3ADIR2%3Adjrdkfawoqihigoett4g6auz6a%3Ajx5mplfpwexnoqff7y5e4zjus4lidm76dcuarpct7cckorh2dpgq/ the publically writeable directory through testgrid.allmydata.org].  Here is [http://testgrid.allmydata.org:3567 the welcome page] which has a list of connected nodes, recent uploads and downloads, and performance statistics.

== How To Connect To The Public Test Grid ==

The test grid is subject to being updated at random times, so compatibility
is likely to break without notice. Also note that many upgrades require all
files and directories to be flushed, especially as storage formats change.

The test grid is currently running an 1.0.0-compatible release (see "My versions" on the welcome page for the current version of the web gateway server).

After installing the code according to [http://allmydata.org/source/tahoe/trunk/docs/install.html docs/install.html], copy the
following file into its base directory:

||file name||file contents||
||introducer.furl||{{{pb://todjw7qkb4dgq4fkeo7cqydcu5vneioh@tahoecs2.allmydata.com:52106/introducer}}}||

Then run ''tahoe start''.

We created a shared public directory: feel free to use it for
experimentation -- once your node is up and listening on port 3456, [http://127.0.0.1:3456/uri/URI%3ADIR2%3Adjrdkfawoqihigoett4g6auz6a%3Ajx5mplfpwexnoqff7y5e4zjus4lidm76dcuarpct7cckorh2dpgq/ this URL] should give you access to that directory.

== Test Grid Statistics ==

Usage statistics are available for the public test grid. (Note: tickets #13 and #317 mention other graphs and changes that need to happen on this page)

=== Count of how many clients and servers are connected to the grid ===

=== Space used by the shared public directory ===

This counts the total size of all immutable files reachable through the
shared public directory listed above.

=== Load Average ===

This measures how long a 1 second callback is overdue, on each machine that
connects to the central 'stats gatherer'.
