The sites from which there is PingER monitoring are shown in red below, sites which are monitored by all monitoring hosts (Beacon sites also include monitor sites) are shown in blue, and other monitored remote sites are shown in green. From SLAC PingER monitors about 460 sites, CERN used to monitor about 132 sites, however after re-installing in December 2006) they now only monitor beacon sites (56). ICTP Trieste monitors 105 sites but only has data going back to September 2006.
In India we have four PingER monitoring sites: CDAC sites in Pune and Mumbai, VSNL in Mumbai and ERnet in Bangalore. In Pakistan we also have four five working monitoring sites: two at NIIT/NUST Rawalpindi (one on the Pakistan Educational and Research Network (PERN), the other on a Micronet DSL link), one at the National Center for Physics (NCP) at the Quaid-e-Azam university (QAU) Islamabad, and one at COMSATS university Islamabad . We are also working on getting host(s) within PERNand one at PERN itself. In addition we have 3 remote (monitored) sites in Afghanistan, 3 in Bangladesh, 2 in Bhutan, 9 in India, 2 in the Maldives, 3 in Nepal, 16 in Pakistan and 6 in Sri lanka. The maps below show the location of the sites.
