server is down

just joined this forum in the hope to get intouch with everyone and get their input on setting up users auth and annotation environment. Anybody noticed that server is donw and not responding to users’ API calls? url is throwing server error 500. Any idea if the server is down for maintenance or are they migrating to another DNS? I have actually accumulated some data on the server and now trying to retrieve it as part of my annotation research but am unable to do so. would appreciate your comment on this.
many thanks
