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 incident lasted 10 minutes.
BGP sessions are restoring.

(10:00): There are currently some general routing problems, affecting the majority of the customers at Belgacom. The problems started around 7am this morning. I've contacted Belgacom, and they said the problem would be resolved by 11am.
Unofficially, rumor has it that the police has raided Belgacom because of suspected fraud. Whether this has got something to do with the routing problems is unknown. More details and corrections will follow.
