BPIP was under persistent DDoS attacks. If I understood correctly, the index page was changed to something random like /a11 in order to fool the bot created for this attack. In part, this is also a confirmation
I may make a suggestion. If we have to enter via the "enter" link, is there a possibility to at least place it in the middle of the page? It is almost unnoticeable on mobile devices in the top left corner. Also, some larger font would be great.
