Pui Hin invited to the meeting all the system administrators from the observatories who participated in the facilities tours hosted by Keck and CFHT. Thank you to Jonathan Chock and Kanoa Withington for their hospitality. The tours were interesting.
On November 2 -- Mac Cooper reported that they were having problems accessing gmail from the Summit. The problem had been intermittent for several months but access had became totally unavailable in the last two weeks. According to UH-ITS, the path to gmail.com was changed to prefer the Pacific NorthWest GigaPOP (PNWGP) when the Time Warner path was saturated before its upgrade. Although the problem with the PNWGP can be fixed, it was easier to simply move the commodity traffic back on the Time Warner path.
Mac Cooper and Simon Chan also reported that routing paths between Cambridge and Hilo and Chile and Hilo are asymmetric, resulting in some problems for SMA periodically. Pui Hin asked Mac Cooper to send her some traceroutes for UH-ITS to use to investigate the problem.
On November 28 and 29 -- Due to maintenance at UH Hilo and to UH-ITS 10Gb upgrade work on the Big Island, network traffic from Hilo to Oahu and to the Internet was rerouted via the microwave between 8:30am and 10:00am on November 28, and between 8:30am and noon on November 29. The SX South was not affected.
On December 1, around 10:30am -- A break in the trunk fiber at the Honokaa Hospital, a site that houses INET optical amplifier, resulted in INET outage in the Hilo area until 3:00pm in the afternoon. Traffic from Hilo to Oahu and to the Internet was rerouted via the microwave. The SX South was not affected.
Kanoa reported that CFHT is still having FTP access problems from outside of Hawaii. Pui Hin will follow up with UH-ITS.
For the interisland upgrades: we are close to having a direct 10Gb link between the Big Island and Oahu, while the connection between Maui and Oahu will not be available until early next year.
The following lists of tasks performed on November 28 and 29 give you an idea of the work involved in the 10Gb upgrade
On November 28:
. Install a second channel at the North Hawaii Education and Research Center facing Mauna Lani for future activation.
. Install a LuxN box at CFHT, but it will not be in service until INET fiber is extended to the facility.
. Install a new router at UH West Hawaii.
On November 29:
. Upgrade of the two 1Gb connections to 10Gb connections between the IfA Hilo Building and UH-Hilo and between the IfA Hilo Building and Hawaii CC.
Note: This meeting has been moved to the IfA Hilo Building since Kiaina will be on travel on March 8th.
