@AngryChicken it doesn't matter wether it's done on your local or the online - if the network is forked, either of the forks could become the real one. It's the transactions on the "wrong" fork that take time to resolve. When the fork happened yesterday, two of the online wallets were on one branch, the other two on the other one. There's no guarantee that your local is correct, it's equally likely to be on the wrong one.
Basically, check the network state before doing any significant transfers/purchases/sales.
