Hi,

I'm in bitcoin for a few months now. Up to know, never had any issues.
However, as of about 24hrs ago, none of my transactions seem to go through?
they all remain unconfirmed.

I've done transactions during the last few weeks, without any issue, using the lowest fair fee.
They always got confirmed (6 confirmations) within about 6 to 10 hours, where the first confirmation came in within the hour.

Since yesterday 07-jun-2016, 22:00 hrs (CET), none of my transactions got confirmed, even the last one, where I added the maximum recommended transaction fee, not any confirmation 2 hours later

Is there an issue or a change globally? Is it me, or just bad luck for me? Or .... ?
And how can I fix it? Because at the moment, it looks like I can't make any transactions anymore

I'm using Bitcoin Core version v0.12.1 (64-bit)

example of the latest tx id : https://live.blockcypher.com/btc/tx/5f5e6a542c04fa299fca80159d25e93fe8d3fb5dc33c0728363f1b8a65ec3b94/ for 0.02 BTC (with the highest recommended tx fee)
example of the first tx id (still not confirmed today) : https://live.blockcypher.com/btc/tx/0f5b2172714c91c4c65ad609a9d7c567bb3f74622c00bb859181dd2a56cc7672/ for 0.0051 BTC (I admit, with a very low tx fee)

Thanks for any feedback
