Warren continued to work on MDS and implementing the EDG WP7 network monitoring schema. Warren is also working with several groups to employ the network data served from MDS.


A new beacons list was issued and deployed to PingER sites.

Several anomilies arose in the script. Warren is working on fixing them.

A new Pinger site at the Pacific Northwest Gigapop (PNW) was setup. However, there is limited peering and some sites cannot reach it.

UMD replaced the former PingER machine and rejoined the monitoring.

A new group ICTP was added to the PingER lists to group members of the eJournal project.

Les sent email to several contacts to revive their reverse traceroute servers.


Les began a new project and kicked off the monitoring of the Electronic Distribution of Academic Services (eDAS) by sending email to possible collaboarators. There were 5 replies in a day from India, Guatemala, Mexico, Philippines among others. Started monitoring some hosts and worked with others to unblock or clarify things.

Les added more ICTP sites for Pinger, now have 6 in MD, IN(Hyderabad, Kerala), GT, ID and BR. Working with 6 other sites to resolve issues, mainly ping blocking.
