V2 Onion Services deprecation →

v2 Onion Services

If you are an onion site administrator, you must upgrade to v3 onion services as soon as possible.

As we announced last year, v2 onion services will be deprecated and obsolete in Tor 0.4.6.x. As of April 2021, Tor Browser Alpha uses this version of Tor and v2 addresses no longer work in this and future versions of Tor Browser Alpha.

When Tor Browser stable moves to Tor 0.4.6.x in October 2021, v2 onion addresses will be completely unreachable.

Why are we deprecating v2 onion services? Safety.…
