perfSONAR User Q&A and Other Discussion

[Piotr Pikusa <>]

Hi Takatoshi, Jason!

I see that Takatoshi tries to connect with RRD MA developed by GEANT. In 
the new version of RRD MA url has changed from geant2-java-rrd-ma to 
perfsonar-java-rrd-ma, but the old one stayed on server to perform 
re-direct. In psUI redirection works fine.

Regards
Piotr Pikusa
