 Ijson provides several implementations of the actual parsing in the form of
 backends located in ijson/backends:
 
-- ``yajl2_c``: a C extension using `YAJL <http://lloyd.github.com/yajl/>`__ 2.x.
+- ``yajl2_c``: a C extension using `YAJL <http://lloyd.github.io/yajl/>`__ 2.x.
   This is the fastest, but *might* require a compiler and the YAJL development files
   to be present when installing this package.
   Binary wheel distributions exist for major platforms/architectures to spare users
   from having to compile the package.
-- ``yajl2_cffi``: wrapper around `YAJL <http://lloyd.github.com/yajl/>`__ 2.x
+- ``yajl2_cffi``: wrapper around `YAJL <http://lloyd.github.io/yajl/>`__ 2.x
   using CFFI.
 - ``yajl2``: wrapper around YAJL 2.x using ctypes, for when you can't use CFFI
   for some reason.
