Today Wednesday 13/05/2015 at 12:20 UTC+2 an installation engineer working on the PE under maintenance in EQUINIX AM3, while testing one of the newly installed 100GE modules, accidentally placed a loop on the ISP peering VLAN.
The loop caused a high CPU on all backbone and customer modules resulting in many BGP sessions dropping.
The incident lasted 10 minutes.
BGP sessions are restoring.
Date: 2015-05-13 11:48:23 UTC The majority of BGP sessions has flapped.
We will contact the exchange point to get more information.
