In its Google Mobile Help Forum, Google just confirmed that the company's free sync service has serious problems at the moment; at least with certain devices. A Google employee officially confirmed that Google Sync is having some difficulties due to an extended problem with one of the company's datacenters. This has been going on over the weekend, but it's got significantly worse today. While Google said that none of the user's information has been lost, and users are still able to get the data through a manual sync, the push functionality isn't working very well. According to Google this is because the company is "batching up fetch requests to be able to cope with the traffic it's seeing while this problem is ongoing".
Google also confirmed that this problem only affects the iPhone, Windows Mobile and S60. Users of another smartphones (Google mentions the BlackBerry sync application and Android sync) should be unaffected by this problem.
While Google is working to get this fixed, there's no ETA given at the moment: "We're doing everything we can to improve the situation in the meantime. Finally, I want to apologise to everyone - we're feeling your pain too, and we will get this sorted out as soon as we can" the Google employee added.
UPDATE: In the latest staus update from last night, Google said that the service is still not completely back to normal but the experience a much more smoother now which should result in seeing "mostly proper" push once again.
