Hey Ludovic V., it should be back up and running now :)Just a few things that the team will fix soon (very likely tomorrow) related to the post by Yash in the Announcements channel, but overall Clay should work fine.
Thanks for reporting, I just ran a test and it appears to be a Datagma issue. Seems like they also have a 503 error "service unavailable" issue going on. Other providers working though
