Increased VPN attacks

Anyone else noticing a massive increase in credential spray attacks on your VPN connections as of the last week or two? We've always had the occasional scans and automated attempts, but lately our SSL-VPN ports are getting hit non-stop with bad login attempts from all over the world. Setting the SSL-VPN host settings to only accept connections from a few required countries cut down on the noise a ton, but still seeing lots of attempts. Checked the logs on my gate at home and am seeing the same thing there.
