Yes, it can happen... Black Friday with a crash in Piraeus Bank's e-banking, and of course nothing happened... not a word was mentioned by the bank or by the journalists.
Many were unable to connect via e-banking on Friday, November 28, as deadlines for important payments were expiring. 
The system outage affected almost all of the bank's digital services. The quick login function with PIN was not responding, while in many cases the confirmation of transactions via token did not work. There were also others who reported restrictions on cash withdrawals from specific ATMs, which caused great inconvenience to those who needed cash. It was Black Friday.
The Piraeus call center automatically hung up calls, leaving its customers without the possibility of information or technical support. Of course, even if the call center is working, by the time the music on hold ends, you have forgotten the reason for calling...
Until late Friday evening, Piraeus Bank had not published any official announcement about the causes of the problem or the estimated recovery time.
The crash of Piraeus Bank for over 5 hours and the silence from the media proves the value of money and shows us how easily we can be left without euros.
Although the press releases will range from very select to rare, I said I'd pass...because sometimes the editors hide.
Guys from iguru, have you gone too far with the clickbait, with such tricks and with the Windows keys, do you think you will survive? You are wrong.
There is no silence in the media, one has to do a search and one finds dozens of websites that say that ebanking and its systems have collapsed.
Such incidents happen and will happen again. The point is that they are fixed and in 2-3 days we have already forgotten about them.
But it was another opportunity for the various gullible people to start talking about the hypothetical evils of electronic money, that we will starve and the like.
Let them go to any other place outside of Europe and the West, to Russia, to China, to South America, to Cuba, to Africa, to the Middle East, to see how beautiful it is there and if they are hungry. After all, that is why people leave by ship to the West, because where they live they have no destiny in the sun.
But the omniscient Greeks inexplicably become propagandists of anti-Western logic.
So all is well for you, Berto, the rest are becoming propagandists, it's time to scrape them and scrape them again since they are happening and will happen again, cross-legged and frappe, although the drink has finally lost its semantics
The behind-the-scenes collusion of the press and financial power was exposed.
Dumb in the ass, everyone owed money on loans and cards, who can you blame since tomorrow you'll need them to give you an advertising listing????
And this morning my husband went to pay with a card, he couldn't, it said "check your bank" and he couldn't even withdraw money from an ATM.
He blocked my codes and I couldn't reset them because I don't have a physical debit card. The first appointment on 9/12 with a foreign I banking
Now imagine if there were no cash and such a long-lasting “malfunction” occurred. Long live digital money.
Will such a long-lasting malfunction occur and you believe that the butcher will sell you meat for cash? Or do you believe that the huge supermarket will be able to make new purchases while the banking system will be out of operation? Or do you believe that the HEDNO or EYDAP technician will run to fix the fault while he is fasting? We will eat each other, we say.
They are doing a good job, everyone has gotten used to paying with a card even for a bottle of water from a kiosk, but we don't know that we are helping them in their work, wake up.
What are you all shouting? You wake up and wake up in your sleep. Why do you have a choice or do others decide for you? I say good night, it's late now.
and for a piece of gum, I'll give a card. The state forces me to make 30% of my expenses with plastic money, otherwise, it will fine me. But I don't see you addressing those who force me to use the card. Of course, even cash receipts don't build tax-free. So cards everywhere, why should I pay the fines?
Bank for crying…
To the accuracy of many users, the accounts were locked both in the app and on the web on Friday afternoon. The call center did not operate until Saturday afternoon. Reissuing the password by any means until then was impossible. However, the Bank, for reasons of impression and communication, had taken care to send messages of an apologetic nature since Friday evening that the malfunction had been corrected.
