Dear Colleagues, We are working on the LIR Portal and back-end systems at the RIPE NCC. Due to this work, we need to perform regular upgrades to our services and this may involve some downtime for the LIR Portal. We have been planning these upgrades on a case-by-case basis, but we believe it would be easier for everyone if there was a regular, fixed maintenance window where possible. Such a window already exists for maintenance of the RIPE Database, so we will use the same window for the LIR Portal: Wednesdays, 16:00-19:00 (UTC) Uptime of the LIR Portal will not be guaranteed during the maintenance window, although we will of course try to minimise downtime. We apologise for any inconvenience this may cause. If you have any comments or questions, please contact us at sw-bugs@ripe.net. Kind regards, Tim Bruijnzeels Service Manager LIR Portal RIPE NCC
