O_SA's blog

This is the second time this happened to me during the contest. I thought the problem was from the country, so I turned on the VPN, but nothing happened. This made me delay sending B by about 5 minutes and sending C also by about 10 minutes. Please, if this was verified by the site organizers, then cancel it. If it was from my browser or something that came back to me, then I am sorry about this blog. Thank you.
