Thanks to a lot of input from members, we now have updated code which should improve the usability and reliability of the information provided by the API. The biggest change is in the sorting rules. The overall reliability is now calculated on a combination of stats from the past 3 months, the past 1 month, and the past 1 week. What this does is weigh heavily towards how the server has performed most recently. For example, any multi-hour outage occurring within the past week will likely knock a server off the list of results a user will see, but outages within the past month may only push the server down a few places. I also added an adjustment for the length of time an admin has been hosting public servers for opennic. The overall formula was readjusted, so distance has the largest impact on a server's position in the list of results, a server's reliability has a somewhat less impact, and the admin's length of time hosting has a fairly minimal impact.
The list of results has also been sorted so that the first 66% of results will all be provided by unique admins. Note that since the nearest-server page results are randomly sorted, two servers from the same admin may appear together, however at least 3 of the four results will be from unique providers. If you wish to modify this result on the API page, you can add the variable ?adm=x to the URL, where x is the number of unique admins you want returned. For example, if you wanted a list of 10 results hosted by a minimum of at least 4 unique admins, you would use ?res=10&adm=4.
Since the server data has all been moved to LDAP now, I am also able to include whitelisted servers correctly now. If you add ?wl to the URL, you will see some servers marked with (w) indicating whitelist-only access. Note that in all cases, you will always have at least one non-whitelist server in your results to ensure that you are still able to do lookups immediately after your IP changes.
For those who haven't seen the other recent changes, there are two other important variables that can be passed. Using ?rnd=true will randomly sort the results. Adding ?ipv=all will give you a list that includes both IPv4 and IPv6 server addresses (note this defaults to showing the IPv4 address if a server has both types). If you want ONLY IPv6 addresses, you can use ?ipv=6.
You can always see the full list of options here: https://api.opennicproject.org/geoip/?help
