I understand you could always pay a higher fee, but for a layman it would be an issue, just as customers couldn't reach their bank accounts. But I guess as adoption increases, so will fees eventually - fees at 1 s/byte will probably not be viable in the long run.

Danske Bank and many other Danish banks DDoS attacked by Russia yesterday

> Overflooding the pool of transactions could be one such attack - we have seen similar cases during bear markets where the pool just got completely filled and you would have to pay double digit sats to make a transaction. 

That's not really a problem and not really an attack. You can always pay higher transaction fee if you want your transaction to be confirmed fast. If you are not ready to pay that, probably your transaction is not so important after all.
