Load Balancer Traffic (Geo) Routing failed

Yesterday Mar 3rd 2023 around 05:30 UTC time, My website faced a huge issue as the geo routing which I enabled in load balancer failed miserably.

I have enabled load balancer for my website and enabled traffic routing policy as geo routing.
According to my settings, all requests from asia are routed to a asia server and all others to a europe server. Everything was working good for last month. But yesterday, All requests from INDIA were routed to europe server for about an hour. I dont know how it happened. But it impacted me hugely.

Can you tell me how it happened?

Does anyone encountered this issue?
