Huge difference in cloudflare traffic stats when moving server


I have a copy of my website .COM.AU on two servers at the moment for testing performance before I try a migration

Server 1 Sydney
Server 2 Singapore

My normal server is Sydney. However when I change my DNS A record to the Singapore server to test it’s performance values ect ect, my website gets a huge increase in traffic

My normal traffic on my sydney server shows about 400 per day. But when I move my A record to the singapore server via Cloudflare traffic is showing about 1500 to 2000 as per Cloudflare stats

What could this be?

I could not possibly be getting more traffic due to a geographical server change could I? as drastic as this?
