Sever Not Appearing on the Server List

It’ll show up in my history, but ever since we moved our server from NFO to OVH, the server stopped appearing on the master list.

EDIT: It does appear, but it takes quite a bit of time for it to. Is this because it’s in a different country? Can I manipulate it so show up on all of the server lists without a day using sv_region?

Um, open up these ports:
27015 TCP/UDP
27020 UDP
27005 UDP
51840 UDP
