Ask HN: Is Facebook having serious database inconsistency problems?
5 comments
I had the experience that some private messages disappeared, the people i send those never got them. It happend more than once where i am sure about it. Maybe i did something wrong but there is no way to find out.
Since then i never send important messages any more over facebook. There is no way you can be sure they got the messages or can find out why they don't got them. E-Mail feels less like a black box.

I've never had those problems, but it could very well be that I never actually knew about them and just assumed people would not reply to me or assume they got my message.
I have seen one other strange behavior. My wife and I use the same laptop. She had logged into FB. When I was using it, i signed out of her account and signed into my account. I then saw some posts from my wife's friends who are not my friends. Strange.
I think a database inconsistency is unlikely, though possible, I imagine they would be very on top of that. It is more likely a caching or replication issue (maybe to do with their new data center -- entirely speculation).
I am also facing the same issue. Number of facebook likes for my sites is also inconsistent. Change in the number is not that significant, however, the inconsistency problem is there.
Confirm. I have same issues with groups.
p.s. I noticed this only in the groups product.
