Yahoo Mail down as UK users are left unable to send emails for over 10 hours
The majority of the complaints refer to users being unable to send emails from iPads and iPhones
YAHOO Mail users in the UK have been left unable to send emails for over 10 hours.
Customers are still complaining on Twitter that their messages are not sending.
The majority of the complaints refer to users being unable to send emails from iPads and iPhones.
An administrator on Yahoo's user forum said: "It has come to our attention that several customers are experience temporary errors or are about to start seeing them.
"This could be any error number as its a large outage. Our engineering team is aware and is working to resolve this issue as quickly as possible."
The beleaguered online company added that some customers had reported improvements to the service but that others should "be aware that it will take some time to get the servers back up and running so you may still get temporary errors as you access your mailbox."
The servers appear to be predominantly down in the UK and Western Europe but parts of the east and west coasts of the US have also been affected.
One Yahoo user on Downdetector.com said: "Unable to send. Two messages in outbox, one from 11pm last night, the other from this morning. Have tried re-sending both but failed miserably."
Another added: "Can receive but not able to send for at least the last 12 hours," while another claimed that had experienced issues with Yahoo Mail for 13 hours."
The breach, which occurred in late 2014, was confirmed by the company, which revealed huge amounts of personal information had been stolen in the "state-sponsored attack".
"The account information may have included names, email addresses, telephone numbers, dates of birth, hashed passwords (the vast majority with bcrypt) and, in some cases, encrypted or unencrypted security questions and answers."
It said that its ongoing investigation found that the stolen information did not include unprotected passwords, payment card data, or bank account information.
In the statement, it confirmed that information associated with at least 500 million user accounts were stolen with the company now working with law enforcement.
The statement said: "Online intrusions and thefts by state-sponsored actors have become increasingly common across the technology industry."
Yahoo said it was notifying potentially affected users and encouraged users to review their online accounts for any suspicious activity.
Verizon, which bought Yahoo for USD$4.83 billion in July 2016, said it had been notified of the massive breach.
It said: "Within the last two days, we were notified of Yahoo's security incident.
"We understand that Yahoo is conducting an active investigation into this matter, but we otherwise have limited information and understanding of the impact."
"We will evaluate as the investigation continues through the lens of overall Verizon interests, including consumers, customers, shareholders and related communities."
