1. Search CID in the address bar
2. see ipfs loading logo
3. try to click on anything else on the screen

Desktop (please complete the following information):

• OS: macOS catalina
• Browser chrome
• Version 89.0.4389.114

Notes from triage:

• ipfs-webui should be smarter about content that is not in local datastore
• if it is not in local cache, show new page for "looking for content"
  • details TBD, rough ideas:
    • always show "cancel" option (js-ipfs-http-client now supports AbortSignal)
    • > 5s provide information that content is not present on local node and is being loooked for
      • bonus: we could visualize the DHT walk – see https://github.com/ipfs/ipfs-webui/issues/1843
    • >ns "taking longer than expected, would you like to manually connect to peer" + input
• see if we can proactively detect CIDs "broken by a typo (https://github.com/ipfs/ipfs-webui/issues/1739#issuecomment-850438099)

We don't have bandwidth for this specific issue right now, but this kind of visibility into network operations would be very useful (e.g. for this IPNS issue)

This information isn't offered by the current RPC API, but we definitely want to expose this in Helia. After that's done, we can expose the info in a GUI.

For visibility, here's the GUI roadmap.
