“Our top priority right now is getting this fixed,” the Yahoo Customer Care account added.
“We appreciate your patience.”
As of 10 a.m. the Customer Care twitter account said most services were back online.
Yahoo customers tweeted at the company, complaining of being unable to send email, complete important transactions or to update their fantasy football teams.
Even the Yahoo Help page didn’t appear to be working just before 2 a.m. PT on Thursday.
In a tweet at one user, Yahoo Customer Care said it could not provide a specific time for when the issue would be resolved.
