Alas! Owing to the political turmoil in your country, Sri Lanka, and the condition of the economy there, I'm not sure that tracking, let alone a diagram of it is possible. Not bing located in Sri Lanka it is not possible for us to have first hand knowledge of the state of your country's postal system. Frankly, the best advice that we can offer at present is for you to try to stay safe. Good Luck.
