I have been using Infinit from times to times and it never failed me. Could you tell us a bit more about your infrastructure ?
Since we heavily rely on peer to peer technology, we don't need much infrastructure as file go directly from one user to the other. We just maintain broker servers that enable you to search for other Infinit users and exchange address information so you can connect directly. As for when we actually store data (links generation feature), we use GCS and/or AWS as a backend.
