Halo fella coders, I'm a coder from Vietnam, Southeast Asia. Is there anyone from any relative country struggling from lags or can't access to the web lately or having Cloudflare error notifications from accessing the web. I'll be really appreciated if anyone can tell me if that's only me that is suffering from this or is there anyway to fix it, thank you so much:D

Heloo coders, happy Lunar New Year to everyone. I'm here today to ask about the scoring system on codeforce especially in the contest scores. Firstly, in div3 the score is usually like + +1 +2 +3 +4 +5,... I don't know how that works. (I do understand how pen works tho) Secondly, in div1 div2, although the submit is full AC, people have different scores from each other, some even have negative red scores. I would really appreciate it if anyone can explain this to me, happy new year again and have fun coding.:D
