Dear colleagues, The webserver that distributes RIS files, data.ris.ripe.net, as well as ftp.ripe.net and data-store.ripe.net, will be down for maintenance on 25 July. During the maintenance, a storage appliance will be moved to a different data centre. This is part of the RIPE NCC’s effort to reduce our data centre footprint and increase the geographical distance between our data centres. BGP sessions with RIS collectors will be established as usual, and no data will be lost. However, downloads from https://data.ris.ripe.net will not be available. Other RIS services are not affected. Start: Friday July 25, 2025 11:00 UTC End: Friday July 25, 2025 15:00 UTC Affected: * data.ris.ripe.net * ftp.ripe.net * data-store.ripe.net We expect service to be unavailable for two hours in this window. Kind regards, Ties de Kock RIPE NCC
