Yes.

It sounds like the mirror may have a wrong-ish implementation of HTTP 
Compression. (See https://en.wikipedia.org/wiki/HTTP_compression) I've 
seen similar oddness dependent on the client request headers.

This might be something to bring to the attention of Facebook or GNU, 
since that's a GNU mirror.
