Yahoo! has bewildered some of its email users by freezing them out of their accounts for what it has described as "scheduled maintenance" to the system.
"We are undertaking some essential, but extensive maintenance to improve Yahoo! Mail. During the maintenance period, some users may experience problems accessing Yahoo! Mail," reads a message from the struggling internet company to users who are currently unable to gain access to their email.
"We sincerely apologise for this inconvenience. Your account is in great shape and we are working to have it available again as quickly as possible."
There are plenty of anecdotal reports via Twitter suggesting there is mail trouble at Yahoo! Towers currently.
Reg reader Paul, who has a BT Yahoo! account, told us that he had spoken with a UK Yahoo! support worker, who confirmed the mail systems were offline for some users.
Apparently, Yahoo! email could be out of action for up to 24 hours for those affected by the apparent maintenance work. We've asked Yahoo! to comment on this story, but it hadn't immediately got back to us at time of publication.
Just last week Yahoo! rolled out its overhauled email service and removed the beta tag from its online mail product. It also slotted more social media elements into the system. But the makeover has so far received at best an underwhelming response.
It's unclear if the maintenance is related to glitches in the latest version of the service. ®
