Dear colleagues, We are planning to replace the pipeline that generates MRT dump files publicly available from the RIPE NCC. The new pipeline will have significantly less delay, and also some changes on the structure of the MRT file format [*]. Files in the newer format are available for testing here: https://www.ris.ripe.net/dumps-per-rrc-rest/prototype/ We have received feedback from MRT parser implementers that these files work fine for their parsers, but in case you haven't tested your MRT parser implementation, we ask you to test the new files before we make the switch. Our plan is to make this switch on 3 April 2023. After we make the switch the bview files available at our main location for downloading MRT files will be generated using the new pipeline and we will be able to produce these files in a more timely manner. Kind regards, Emile Aben RIPE NCC [*] These changes are documented here: https://ris.ripe.net/docs/40_Prototypes/15_per_rrc_dumps.html, but beware at this point we are only changing the files, not the frequency of dump files, nor putting the API in production. We did not receive feedback about these, but please let us know if you find them useful.
