[Apologies for duplicate e-mails] Dear Colleagues, Due to the instability of our network over the last week, we will perform emergency maintenance today, 4 July 2006, from 16:00 - 19:00 (GMT). During this maintenance there will be disruption to the RIPE NCC network and its services. The instability is due to a problem with our firewalls. Our supplier is working to resolve the issues. We will remove the affected firewalls from our network until we are confident that these issues have been fully resolved. This will prevent any further related network outages. We apologise for any inconvenience this may cause. Regards, Brian Riddle IT Manager RIPE NCC
