About 20% more traffic in India

over the last week something lead to a ~20% traffic increase on all my pool servers located in Mumbai.
Usually I have (in sum) about 100k req/s, now the servers get 120 to 130k req/s.
The traffic is mostly coming from India, some requests from China and Brazil - but IIRC this has been the case before. Unfortunately, I have no more detailed data I could compare the current traffic with.
Does anybody experience the same? Has something changed, i.e. regarding Geo-DNS?

I just have the one server in Mumbai and can see the normal slight changes from week to week but nothing like you have seen. I did make some changes myself a few weeks ago that you can see in the graph.
