There is a distributed attack on our git over https service. Lots of git clone https://sourceware.org/git/... https://cygwin.com/git/... and https://gcc.gnu.org/git/... from lots of different ip addresses.
For now we have disabled git-http-backend.
Please use either the git:// or ssh:// protocol to clone the git repos.
gitweb and cgit are still functioning. But this does break builder.sourceware.org buildbots and forge.sourceware.org mirroring.
Suggestions to block these git clone bots welcome.
