I'm with my dgb locked in confirmations, what happened to the network?
https://digiexplorer.info/I didn't find any problem with blockchain it working fine you should provide more details what happened actually with your transactions. I hope in next couples of minutes it will get confirmed.
(4562 confirmations) does this usually happen?

Do transactions get confirmed? Yes, confirmation every 15s on average.
It has been almost 19 hours that are confirming, and I have not received, what is the minimum of confirmations?
Have not received where? It's on the blockchain, so it is where you sent it.
I've got to go so I'll take a wild guess and imagine you sent to Poloniex they recently uped the confirmations required to 6000, a ridiculous number but they did it because someone managed to perform an exploit in the middle of last month. It's been fixed since then but network mining needs to exceed 51% on the latest version of core and I'm not sure if it is yet.
