I would have said "move to git.kernel.org" but that's also hosted by a US based provider:
organisation: ORG-PHI3-RIPE
org-name: Packet Host Inc
org-type: OTHER
address: 30 Vesey Street, Suite 900, New York, NY 10007 US
And, obviously GNOME git servers are US based, since they're owned by RedHat/IBM.
