ACOnet FileSender Upgrade on 1 December 2020

On 1 December 2020 a new version of ACOnet FileSender will be put into operation. The service will therefore not be available from 20:00 to 24:00 CET. The new system has been extensively tested over the past months.

What will change with the new FileSender?
  • You can upload up to 30 files at once and use several upload processes running in parallel (depending on the quality of your internet connection). The size limit per transfer has been increased to 250 GB.
  • You will receive the download links created by FileSender by e-mail and can conveniently forward them to the desired recipients from your own e-mail address. For more information on this please see the FileSender Wiki.
What will happen during the changeover?
  • The old FileSender system will be renamed to https://filesender-old.aco.net (previously: https://filesender.aco.net). All previously uploaded files will remain accessible until their expiry date.
  • The new FileSender test system will be renamed to https://filesender.aco.net (previously: https://filesender-test.aco.net).
  • All valid download links of both systems will be automatically redirected to the changed server addresses and therefore continue to work.
What will no longer work after the changeover?
  • You can no longer log in and no longer upload files to the previous FileSender system (then: https://filesender-old.aco.net). However, existing download links can still be used until their expiry date.
  • Existing FileSender vouchers ("Invite guest" function) from the previous FileSender system will expire with the upgrade. Instead, new invitations have to be issued on the new system (where this function is called "Receive").
  • If you have used the Python CLI client on the FileSender test system, you need to download it again so that the server name encoded in the client is updated. However, any generated API Secrets will remain valid and usable.

Further information on the upgrade can be found in the FileSender Wiki.
