(NEW YORK) -- Chase apologized to its online banking customers on Wednesday who had a hard time logging onto the bank's website the day before.
For hours on Tuesday, if you tried to log onto the site, you were met with this message: "Our website is temporarily down, but our branches and Mobile Apps are available. Please try again later."
The bank tweeted to customers, "*ALERT* Chase Online is experiencing intermittent issues. We are working to resolve and will keep you updated."
Chase later confirmed to ABC News that it was the victim of a cyber attack called a denial of service (DOS). The site has since been restored.
"*UPDATE* http://Chase.com & JPMorgan Online are back up. We're sorry it was such a rough day and we really appreciate your patience," @ChaseSupport tweeted early Wednesday morning.
