Per WP# 6072 -- Activity: PNNL will be coordinating an OTDR test of the fiber pair that feeds the observatory's data connection to make sure that signal strength is appropriate for upgrading to 10Gb/s up from 1Gb/s. Wireless, phones, and internal wired networks at the observatory will be unaffected. Internet access will be interrupted during this work. Work started at 08:00 PT, completed at approximately 09:10 PT. If I receive the OTDR data (as viewed from PNNL - ISB2 end), I will attach it to this post.
