After more than 24 hours of complete uselessness, Chase’s website came back to life late Tuesday night.

The crash left over 16 million Chase customers without online access to their bank and credit card accounts. However, the problem caused no disturbance to credit or debit transactions and the bank says that automated payments were not affected by the disruption.

As of right now, no official explanation has been given for the outage other than “technical difficulties.”
