Using a variety of sources, I have identified a list of all the server locations that ROBLOX uses to host their servers. Use this to make a server list in your game, I suppose.
-
Palo Alto, California, USA
- San Mateo, California, USA
- Los Angeles City, California, USA
- Portland, Oregon, USA
- Dallas, Texas, USA
- Ashburn, Virginia, USA
- Newark, New Jersey, USA
- Miami, Florida, USA
- Atlanta, Georgia, USA
- New York, New York, USA
- Chicago, Illinois, USA
- London, England, The United Kingdom
- Paris, Île-de-France, France
- Frankfurt, Frankfurt Rhine-Main, Germany
- Amsterdam, North Holland, Netherlands
- Warsaw, Masovia, Poland
- Singapore
- Hong Kong
- Tokyo, Tokyo-to, Japan
- Mumbai, India (not available as of now)
And that should be all of them. Most front page games only have servers from San Mateo, because I am assuming ROBLOX’s best servers are there.
Thank you to @GoodNameOnly for knowledge on the India server
