+# The Public Test Grid
+
+## 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.  It is currently running v0.4.
+
+After installing the code according to the [README]source:README, set up a client node with the following files in its base directory:
+
+| | |
+|---|---|
+|file name|file contents|
+|[/testnet/introducer.furl introducer.furl]|`pb://xextf3eap44o3wi27mf7ehiur6wvhzr6@207.7.153.180:56677,127.0.0.1:56677/introducer`|
+|[/testnet/vdrive.furl vdrive.furl]|`pb://xextf3eap44o3wi27mf7ehiur6wvhzr6@207.7.153.180:56677,127.0.0.1:56677/vdrive`|

+## Test Grid Statistics
+
+Usage statistics are available for the public test grid.
+ * count of directories in the grid ![](http://allmydata.org/tahoe-munin/tahoecs1.allmydata.com-tahoe_dirnodes-month.png) [/tahoe-munin/tahoecs1.allmydata.com-tahoe_dirnodes.html other time scales]
+
+ * count of files stored in the grid ![](http://allmydata.org/tahoe-munin/tahoebs1.allmydata.com-tahoe_files-month.png) [/tahoe-munin/tahoebs1.allmydata.com-tahoe_files.html other time scales]
+
+ * average shares per file -- this hints at the number of nodes in the overall grid; If the number of hosts in the grid is less than 100, then shares_per_file should equal about 100/numhost ![](http://allmydata.org/tahoe-munin/tahoebs1.allmydata.com-tahoe_sharesperfile-month.png)  [/tahoe-munin/tahoebs1.allmydata.com-tahoe_sharesperfile.html other time scales]
+
+ * total bytes consumed by all of the Tahoe test grid storage servers operated by Allmydata Inc.
