We will intervene on the loop 3 for the security works(same as what has been done on the Loop 1 and 2, see task # 5763 and task # 5909).
This involves moving DSLAMs uplinks to a new transportation equipment. So there will be a service cut off on each successive NRA that we will try to minimize as much as we can.
We planned a maintenance window of 1 hour by NRA. Works will begin around 22:00.
The NRAs will be impacted in the following order: SAN59, WAS59, RON59, RSA59, STM59.
We will work tonight on the NRAs: SAN59, WAS59 and RON59.
Date: 2011-10-28 12:20:00 UTC The security on pop2 is active. The loop 3 is ... fastened.
Date: 2011-10-28 12:17:26 UTC STM switched.We activate the security links to the pop2.
Date: 2011-10-28 12:16:03 UTC RSA switched,We move to STM.last NRA in loop.
Date: 2011-10-28 12:13:44 UTC We have met difficulties in TOU59. The port of one transport equipment was defective in Roubaix. We have moved the link to another port. The DSLAM is back online. We attack the RSA switch.
Date: 2011-10-28 12:02:55 UTC Switching of TOU59 in progress.
Date: 2011-10-28 12:01:46 UTC RON59 switched.We prepare TOU59
Date: 2011-10-28 12:01:00 UTC We go back to work.We have fixed a problem of wiring on WAS59.We are working on RON59 to prepare the switch.
Date: 2011-10-26 00:16:03 UTC We had too much attenuation between RON and SAN,which prevents us to setup the link under normal conditions. We postponed RON59 failover to the next maintenance on Thursday.
Date: 2011-10-26 00:06:50 UTC WAS59 switched.
Date: 2011-10-25 22:31:03 UTC SAN59 switched,we are preparing WAS59.
Date: 2011-10-25 22:30:03 UTC We are preparing the switching of SAN59.
