After the upgrade caused NIS issues, I’ve discovered some users are locked out of access to web and ftp services here.  If you’re reading this you are probably okay but if you’ve got a weather station or something else automatically doing periodic logins to ftp, you may be blocked.  If this is the case please initiate a support ticket with your IP address or e-mail support with your IP address and indicate that you can not reach the web and/or ftp server and I will manually remove the block for you.
