Lots of companies do this on their websites now using cloud flare or something similar. It’s practical. Still it’s frustrating as a user when you’re traveling over in Europe and can’t access your accounts to pay bills or whatnot.
Next time I travel overseas I'll have a VPN ready.
My bank had some technical problem that prevented access from overseas last time I traveled and I couldn't access my account (which was extremely inconvenient).
Most banks that will work with. For what ever reason the bank I now use knows most vpn providers and completely blocks all traffic from them so using a vpn is not an option either. The “vpn” I’ll have to use is tunneling back to my home ip. It’s actually quite frustrating.
Commercial VPNs are often blocked too. I found a p2p vpn to my home network + ssh socks5 proxy to work well.
