MyASN outage and RIS service degradation
by Erik Romijn 16 Apr '08

16 Apr '08

[Apologies for duplicates] Dear Colleagues, Due to failure of one of our database servers, the MyASN service is currently unavailable. No alarms will be detected and the configuration website is not working. The other RIS tools still work, but their speed is degraded. We do not know when this problem will be resolved, but we will let you know when more information is available. We thank you for your patience and apologise for any inconvenience this may cause. If you have any questions, please send an e-mail to <ris(a)ripe.net>. Regards, Erik Romijn Information Services RIPE NCC
