I have a website where one page received huge traffic in one moment, causing errors 404.
Next day, traffic returned to normal but some percent of this page visitors still receive this error (5-10%).
Other pages on the same website are working without any errors.
Website is Wordpress on Amazon server. If it can have any relation, this page is connected with Mautic.
What can I do to resolve this issue, and also, what can I do to avoid mass errors when next peak comes?
