Planned OS Upgrade on HKIX switches and Relocation of Route Server 1 (RS1) to new HKIX switch
Date: 23-Nov-2014 Sunday
Time: 0001 - 0800 HKT (GMT+8)
HKIX will perform OS upgrade on HKIX switches and reload the Ethernet modules one by one. You may experience up/down events on your HKIX link(s) within 30 minutes during the corresponding module startup. In normal situation, if you have multiple LACP links to HKIX, the links should be connected to different Ethernet modules and the traffic will be forwarded by the rest of LACP links on the same switch.
In addition, HKIX will relocate Route Server 1 (RS1) to the new switch. There will be no impact to HKIX participants which have BGP sessions with both route servers RS1 and RS2. During relocation, your BGP sessions with RS1 will be down but your BGP sessions with the other route server RS2 will NOT be affected and the multi-lateral peering can still be maintained.
If you have not set up BGP sessions with both RS1 and RS2, you should do it ASAP for better resilience.
