Ebay users hit by site problems
Ebay users are reporting issues using the auction website following scheduled maintenance carried out earlier today.
Some users are complaining of log-in failures or problems using the service once they have accessed their accounts.
A spokesperson for the site told the BBC issues had been occurring since around 08:00 BST but added that they were "intermittent".
Site users had been warned in advance that the maintenance would cause disruption, he added.
However the work had taken longer than anticipated, eBay said in a statement.
"We are sorry that intermittent problems with eBay have continued for longer than planned. We are working hard to resolve the issue, and will provide a further update soon," the firm said.
Hundreds of individuals and businesses have been tweeting about the service disruption.
"Anyone else having problems with eBay this morning? Keeps telling me my ID is incorrect (it isn't) and not allowing me to log in. Grrr!" said author Anne Mitchell.
"Anyone else having problems with eBay today, First it's down & then it's up, then logins fail or pages don't work," tweeted hockey shop owner Ken Abbott.
