Hi, Although this is not a new problem (it started on 27 april), I wanted to let you know there are recurring transatlantic problems for UUnet networks in France, Uk, The Netherlands and Belgium (ASes 702, 3259, 1890, 2822, 1849). Symptom is that periodically transatlantic IP connectivity stops for periods between a few minutes to a few dozen minutes but BGP sessions are not interrupted. From UUnet France we have measured 13 outages of over 4 minutes since 1st May for a total of 168 minutes, including 6 outages today! More than just the problems that such connectivity failures cause, the fact that UUnet BGP sessions continue to announce unreachable networks prefixes during outages prevent all multihomed networks to efficiently handle those problems. As you might guess, UUnet has been providing no explanation at all except 1 fax sent to all its customers. The national NOCs seem totally unaware and unable to cope as the problem is transatlantic and handled in the US. There is no equivalent of www.noc.uu.net for european networks... What you should also know is that European UUnet networks are peering with very few networks other than their transit customers and that they rely on AS701. When transatlantic connectivity fails like this, most of the internet becomes unreachable. This message is not sent here in order to make UUnet react; we have already put the necessary pressure locally including public statements with no reaction at all. This is just to inform the community how european UUnet customers are treated. It is significant of the general low level of communication that European ISPs have with their customers, at least compared to the US. JP Donnio network consultant Attachment:
