If you use Google Sync to get your GMail then you’re probably not a happy camper today. This is the post from Google in their forums:
As many of you have noticed, Google Sync is having some difficulties due to an extended problem with one of our datacenters. This has been going on over the weekend, but it’s got significantly worse today, so I’m just letting everyone know what’s happening.
None of your information has been lost, and you will still be able to get your data through Sync, but you will find that Push isn’t working very well. This is because we’re batching up fetch requests to be able to cope with the traffic we’re seeing while this problem is ongoing. As soon as we’ve got the problem fixed, push should seamlessly start working properly again.
We’re working flat out to get this fixed, but unfortunately we don’t have an ETA at the moment. We’re doing everything we can to improve the situation in the meantime, and I’ll post here again when I have more news.
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.
I should add that this is affecting Google Sync for iPhone, Windows Mobile and S60 – if you’re using another way to sync with Google (the BlackBerry sync application, Android sync and so on) you should be unaffected by this problem.
If you use Google for your email you should probably just not use Goog Sync for now and instead pull your email.
