Welcome to China,
haha.
No. Actually my connectivity is relatively
good, and I have plenty
of bandwidth and being able to visit
many of the U.S-based servers
directly with a reasonable speed,
such as CloudFlare or Amazon CDN
(they do have local servers
but still direct most users to the U.S.
due to high ISP costs).
However, apparently Hydra is not one of them. I believe
censorship
is less relevant to this specific issue, this looks
like a network
routing/capacity issue, as usual. People from
other parts of the world
may also have similar problems.

Yes,
that's what we all know.
I'm not CloudFlare fan but I
have to say, there isn't an
intentional plot against Tor
users because any IP address-based
firewall would eventually
blacklist all exit nodes, and yes,
they (and any other large
providers, e.g. Google Search) need
to work with the community
to solve this issue.
For this mirror, I have switched all
security features off or to
the minimum level by using a
CloudFlare Page Rule.
I'm able to access via Tor without
blocking by its firewall, I
don't know if it's just for my
lucky exit node through.

It is very low.
By default, CloudFlare seems to be
conservative on caching, I have
seeing lots of people
complaining that CloudFlare talks to the origin
too frequently
and effectively change a DDoS into a DoS (lol). Some
tuning may
help. I think it is beneficial for users even if it acts
only
as a reverse proxy. I can tweak the settings a bit after more
people started to use it.
