<p><a href="<page docs/bridges>">Bridge relays</a> (or "bridges" for
short)
are <a href="<page docs/tor-doc-relay>">Tor relays</a> that aren't

That means that ISPs or governments trying to block access to the
Tor network can't simply block all bridges.

<p>Being a normal relay vs being a bridge relay is almost the same
configuration: it's just a matter of whether your relay is listed
publically or not.
publicly or not.

<p>Right now, China is the main place in the world that filters
connections to the Tor network. So bridges are useful a) for users
in
China, b) as a backup measure in case the Tor network gets blocked
in
more places, and c) for people who want an extra layer of security
<p>
So bridges are useful a) for Tor users in oppressive regimes,
and b) for people who want an extra layer of security
because they're worried somebody will recognize that it's a public
Tor relay IP address they're contacting.

Several countries, including China and Iran, have found ways to
detect and block connections to Tor bridges.
<a href="<page projects/obfsproxy>">Obfsproxy</a> bridges address
this by adding another layer of obfuscation.

<p>So should you run a normal relay or bridge relay? If you have

of bandwidth, you should definitely run a normal relay &mdash; the
average bridge doesn't see much load these days. If you're willing

If you're willing
to <a href="#ExitPolicies">be an exit</a>, you should definitely
run a normal relay, since we need more exits. If you can't be an
exit and only have a little bit of bandwidth, be a bridge. Thanks
