PingER has been deployed for several major communities:
- The High Energy and Nuclear Physics (HENP).
- ESnet community.
- For people interested in
quantifying Internet access for the Digital Divide
- The Cross Industry Working Team (XIWT)
HENP, ESnet and the Digital Divide
In January 2005, in this community there were
about 30 active monitoring sites
in 14 countries,
726 remote sites in 123 countries,
monitor-remote-site pairs, and about 54
The 106 countries between them have over 78% of the
world's population and over 90% of the online users of the Internet
Nua Internet Surveys). PingER is thought to be the most
Internet performance monitoring project in existence.

Maps of the deployment by state & province for U.S. and Canada are shown below.
There is also a map of the Beacon sites.

The XIWT/IPERF group has 10 monitoring sites (Bellsouth, CNRI, Digital/Compaq
(2), DirecPC, HP, Intel, MIST, SLAC & Westgroup). They mainly do full mesh
pinging and have about 150 monitor-remote site pairs. The community of interest
is more commercial (70% .com, 20% .org, 10% .edu) than the HENP/ESnet effort.
