A Changing User Interface for rpki-validator.ripe.net
by Nathalie Trenaman 10 Sep '21

10 Sep '21

Dear colleagues, As we have already announced, we have ended support for our RPKI Validator. We have still been running our Validator 3 on http://rpki-validator.ripe.net <http://rpki-validator.ripe.net/> as an informational service to the community. However, we will be replacing our validator with Routinator on Thursday 16 September. Routinator has a new User Interface, so this migration will change the look and feel of http://rpki-validator.ripe.net <http://rpki-validator.ripe.net/>. In order to prepare for this change, you can try out the new UI that Routinator will use at https://routinator.nlnetlabs.nl <https://routinator.nlnetlabs.nl/> More details are in our RIPE Labs article at https://labs.ripe.net/author/nathalie-trenaman/a-changing-user-interface-fo… <https://labs.ripe.net/author/nathalie-trenaman/a-changing-user-interface-fo…> Best regards, Nathalie Trenaman Routing Security Programme Manager RIPE NCC

AS5400 -- British Telecom contact?
by Ronald F. Guilmette 04 Sep '21

04 Sep '21

Do any of you folks happen to have a networking contact within British Telecom that you could share with me? I tried emailing then at network(a)bt.com but got no response. I suspect that their routing of 169.129.0.0/16 is, um, inappropriate.
