The FileSender project uses the Assembla project hosting service to host its documentation, code and tickets. Assembla was down for 10 hours on 24 February 2015 and as a consequence both www.filesender.org and it’s redirection target https://www.assembla.com/spaces/file_sender/ were unavailable.
Assembla has published an outage report:
“for about 10 hours starting at 03:15 UTC on 24 February. All services are restored with no data loss. – See more at http://blog.assembla.com/assembla-was-down-here-is-the-explanation ”
New systems do generate new problems, but sometimes also old and well-known problems 😉
