We disabled MPLS on our backbone yesterday night.
Apparently the order has not been taken into account on all routers correctly. We have just remade it on some routers:
p19-7-6k(config)#no mpls ip
Some customers on P19 may have a traceroute disconnection to some IP in Poland or in Spain.
Update(s): Date: 2010-07-28 23:16:04 UTC
MPLS is disabled on the internal network at Roubaix in order to avoid problems on the iscsi of RPS.

MPLS is not the source of backbone crash described here by:
We are going to reactivate it.
