Hi All, Could it be that the API at <a href="http://atlas-ui.ripe.net">atlas-ui.ripe.net</a> is since last night not ipv6 reachable? We are not sure if it was before, but we had to change today the DNS Name to the ipv4, in order for the requests to work.

Some of the topics include: - Investigating customer complaints about slow servers - Comparing TCP and UDP Response Times of DNS Root Servers - Discovering Path MTU black holes on the Internet We’ve collected all of these user experiences, analyses, papers and presentations in one place on RIPE Labs, in order to make it easy to discover how others are making use of the RIPE Atlas network - and maybe spark some ideas about how you can, too. <a href="https://labs.ripe.net/atlas/user-experiences" target="_blank">https://labs.ripe.net/atlas/user-experiences</a> If you have your own story about how you’ve used RIPE Atlas, we want to hear from you!
