EFFECTIVE JANUARY 1, 2024:
Because of the proliferation of web-gopher proxies that don't gate bots,
and because operating the site costs us money directly in bandwidth, we're
forced to crack down. We get literally tens of thousands of requests a day
often from single IP addresses or networks. This isn't acceptable anymore
and is a cost we cannot meaningfully sustain.
We want bots spidering gopherspace to generate publicly accessible indexes
that people can search over Gopher. This is a good use of community
resources. Those sorts of spiders, assuming they obey restrictions and keep
their access rates reasonable, are to be encouraged. We will support them.
Bots that generate publicly accessible snapshots also fall in this group.
On the other hand, spidering away to generate a private index basically
costs us and other sites money for something that doesn't improve general
gopherspace, and those spiders will be banned. Similarly, misdirected bots
that index through misconfigured proxies generate useless traffic, and we may
prevent those proxies from accessing Floodgap altogether until this is fixed.
You're welcome to disagree, but you don't pay the bills. Nothing personal.
ARE YOU HERE BECAUSE YOUR SITE IS BLOCKED?
See the list at the end. Contact us at gopher@floodgap.com if you want to
be unblocked. Be prepared to explain your bot's or proxy's activities, and
do note that we reserve the right to keep it blocked.
REQUIREMENTS FOR SPIDERS:
- If your site is determined to be spidering, the IP you use for spidering
must be accessible on port 70 so we can confirm you are a gopher server.
Ideally your index should also be publicly searchable.
- If you cannot do this, but have a reason to be white-listed, please
E-mail gopher@floodgap.com with a contact person and an explanation.
IPs or netblocks will be blocked WITHOUT WARNING (either at the protocol or
the packet filter level) unless either or both of these conditions are met.
Talk to us first before firing up your bot.
