I got a message today when I tried to go binance.com.
Sorry, the website is unable to access for the moment. According to the filing requirements of China's Ministry of Industry and Information Technology (MIIT), the website is accessible only if the ICP information is accurate and the ICP license is filed.Please contact the person in charge of the website for assisstance.
After 15min it started working but after this sold all my BNB and pulled out all my coins.
They had a system upgrade, read the announcements before you panic sell!
I knew it was upgraded and checked it first thing in the morning, then it was ok - was able to log in and everything. Few hours later got this message and that seemed strange to me. No gain no loss so I decided to sell it and move to another exchange. Just had this great feeling when you cannot access your funds anymore.
Good Luck!
