RRC maintenance announcement
by Erik Romijn 20 Feb '07

20 Feb '07

[Apologies for duplicate e-mails] Dear Colleagues, On Wednesday, 21 February 2007, we will be conducting planned maintenance on the Routing Information Service (RIS). This work will move our Remote Route Collector (RRC) for multihop peerings (rrc00) to a different location, increasing its reliability. The RRC will be shut down between 11:00 and 13:00 (UTC). We will then move the machine to its new location. If no problems occur, the move should take no more than three hours. During the maintenance, no routing data will be collected on this RRC and its Looking Glass will not be available. Other services, including Looking Glass services and data collection for other RIPE NCC RRCs, will not be affected. We thank you for your patience and apologise for any inconvenience this maintenance may cause. If you have any questions about this work, please e-mail: <ris(a)ripe.net> Regards, Erik Romijn Information Services RIPE NCC

RIS Maintenance Announcement: Thursday 15 February, 2006
by Erik Romijn 12 Feb '07

12 Feb '07

[Apologies for duplicate e-mails] Dear Colleagues, On Thursday, 15 February 2006, there will be planned maintenance on the Routing Information Service (RIS). This work will make the RIS database compatible with 4-byte Autonomous System Numbers. At 16:45 (UTC), the RIS database will stop inserting data. Between 17:00 and 18:00 (UTC), the database servers will be stopped twice for about 15 minutes. All RIS tools, except the Looking Glass, will be unavailable for up to 20 minutes. Data collection will continue during the maintenance. When the system restarts, it may be a few hours until all the stored updates are inserted. We thank you for your patience and apologise for any inconvenience this may cause. If you have any questions about this work, please e-mail us at: ris(a)ripe.net Regards, Erik Romijn Information Services RIPE NCC
