downloading – Experiencing slow downloads for Android SDKs in Android Studio

I’ve tried to download SDK sources for Android APIs. Earlier, I used to get well around 100 Mbps, the bottleneck was my internet speed, now I’m getting less than 1 Mbps average speed. I’ve tried 3 different OSes(considering there may be different sources for an OS and traffic maybe more on Windows than Linux) but still the same, anyone else noticed?
