It's much more likely to be a problem with your ISP, or possibly a misconfiguration in your Fedora install.
Just for the heck of it, try pinging with different packet sizes, e.g.:
ping -s 1024 8.8.8.8 ping -s 576 8.8.8.8
and see if some work and some don't. MTU problems can manifest in really wierd behaviour sometimes.
