08:05 → 08:15 Update on progress

a. The 100Gigabit link to JBO – Jimmy The 100G link from JBO was investigated yesterday by the provider of the fibre. They performed OTDR tests to investigate an 8dBm loss in power found on 9th February. They tested the link for 4 hours yesterday and I have not heard the official outcome, but unofficially they haven't found the problem. b. Tests between DTN Lon and DTN Cape Town – Richard & Siju Some connectivity suggestions made to use the Open-exchange path. Richard to check status with TENET and GEANT OPS c. Results of transfer tests between Juilich Onsala, GÉANT– Oleg, Simon, Richard, Domenico d. Feedback on the DMZ work - Network and Storage questions – Mary & Siju Sent the Qaire to Pawsey as well. Had 2hr conversation with SurfSARA and all the questions answered. Not clear if there is a problem with the questions or not - maybe the other 2 sites will clarify this. Richard to push Alison Rohini to ask RAL T1 manager e. Task 2 – Mauro No contact from Task2

Have been cleaning up the data from the web transfers & making the transfers more efficient. Now a member of the LOFAR VO with help from Oleg. This should be more efficient for access/transfers.
