Leaving out the region will assume all regions, leaving out the tier will assume all tiers, leaving out the type will assume both PlanetLabs and SLAC type landmarks. If the region is included then only landmarks in that region will be used. If the tier is specified then only that tier's landmarks will be used. If the type is specified then only that type landmark will be used. Any or all of the tier, region and type region may be specified as "all".

Deployment of Landmarks
There are about 60 SLAC/Looking Glass landmarks, and about 156 PlanetLabs landmarks. We are working on filtering the latter to remove non- or poorly respodning landmarks. The PlanetLab landmarks send 10 pings very quickly, whereas the SLAC/Looking Glass landmarks send five 56 byte pings with one second between them, they will also wait for a deadline time of 30 seconds for pings to be replied to.
You can see a Google map of the PlanetLab and SLAC/Looking Glass landmarks by clicking below or by going to: http://www.slac.stanford.edu/comp/net/wan-mon/viper/tulip_googlemap.htm
