Service stopped October 18; the reason was disclosed October 19. Status follows ITmedia's 13:53 JST report.
Reason explained a day after suspension
Papyless initially described the October 18 interruption as emergency server maintenance. ITmedia reported the following day that the company had detected possible unauthorized access. Details and effects were still being investigated; suspension alone does not establish that user data was leaked.
Arrangements for unread rentals
That morning, the operator said it was working on recovery and considering separate measures for rental works unavailable during maintenance. No specific extension or refund terms had been announced. Renta! is Papyless's e-book rental and sales service. Readers should consult subsequent official notices for restoration and customer arrangements.
