Signal was just one of many services brought down by the AWS outage.

It does temporarily, on the order of hours to days. It's not designed to use the network for long term storage, just message passing

    No, DHT is just a way of determining paths and priority of value lookup by key in the network, so that the load were distributed predictably, while allowing you to find, well, what you are looking for. BTW, while everybody uses Kademlia with modifications, I'd argue that Chord is better for anything related to security and anonymity.

    Storage and serving of anything big is another thing. I take it you mean that I2P nodes cache messages relayed via them when the target node is unavailable. That doesn't have anything to do with DHT.

    I2P has its own internal DHT network. Bote piggybacks on it to relay messages between Bote nodes. You can even configure it so you can address random online nodes and ask them to hold a message for another node to relay (online or offline) to obscure message timing

    DHT can be used for almost anything as a generic key value store, even if the typical use is just peer finding
