Tor network status now available

Further to our last post on May 22, we have now made available an initial step to identify and advise people about the status of the overall Tor network.  This information is now displayed at the top of our pickaproxy.com web site, showing the "current Tor network status" as either Ok, Use With Caution, or Not Considered Safe.  These 3 conditions are initially defined as follows:

"Ok" means there are at least 525 exit nodes ("proxy servers" for the non-Tor-speaking set), 500 relays, 300 guards, 6 version 3 directories, 500 version 2 directories, 32 KB/s mean and average exit bandwidth, and 40 KB/s mean and average relay bandwidth. Any nodes hibernating, marked as "bad", not "valid", or not "running" are excluded from these numbers.

"Use With Caution" means there are less than 1 or more of these thresholds, but at least 375 exit nodes ("proxy servers"), 350 relays, 150 guards, 5 version 3 directories, 250 version 2 directories, 22 KB/s mean and average exit bandwidth, and 30 KB/s mean and average relay bandwidth.

Anything less than any of these Use With Caution thresholds will result in a "Not Considered Safe" status.

Our next step will be to allow people to subscribe to this information, and to define these thresholds for themselves. Our checks to update this status are currently done every 1-2 hours.
