the download server was moved, per https://github.com/rose-compiler/rose/issues/447#issuecomment-1136287462

```diff
- http://rosecompiler.org/edg_binaries/
+ http://edg-binaries.rosecompiler.org/
```

currently, the old location throws useless 404 and 403 errors

* error 404 on http://rosecompiler.org/edg_binaries/roseBinaryEDG-5-0-x86_64-pc-linux-gnu-8.0-5.0.11.80.1.tar.gz
* error 403 on http://rosecompiler.org/edg_binaries/

example ...

```
# /edg_binaries/.htaccess

# directory listing
ErrorDocument 403 /edg_binaries/moved.html

# file access
ErrorDocument 404 /edg_binaries/moved.html
```

Moved

The download server has moved

Old site: http://rosecompiler.org/edg_binaries/

New site: http://edg-binaries.rosecompiler.org/

im proposing a manual redirect to offload the main server

Search the repository for the old http://rosecompiler.org/edg_binaries/ URL and inspect the relevant download configuration, including the .htaccess and moved.html examples mentioned here. Replace the old location with http://edg-binaries.rosecompiler.org/ and verify that download links use the new server without directing traffic through the old location.
