    On Friday, we have been hit by a massive DDoS attack. Since we switched to a service that protects us against such attacks, our IP addresses have been changed.

    If your DNS cache has not been cleared you might have had trouble accessing JotForm site. In that case we recommend using jotform.net instead to log into this site or and to link from your forms.

    It has been more than 24 hours now since the DNS change so it should update for everyone soon.

    Thank you for your patience.
