On 10th March 2021, our hosting provider suffered a major incident when one of the Strasburg data centres was destroyed by a fire.
Unfortunately the systems hosting the uploader were in that data centre, and have been destroyed
All stacks already online are unaffected: they are hosted by the Internet Archive and you can continue to view and run them at https://archive.org/details/hypercardstacks
We hope to have the uploader back online soon. Meanwhile, if you have stack you want to upload, please feel free to email us at HyperCardOnline@gmail.com
Thank you for your patience!
