> At this time, the FTP server appears to be unreachable for all accounts. When attempting to login to the FTP server, you may see the following error message being reported by the server: 421 3900 users (the maximum) are already logged in, sorry Because the online file manager(s) also use FTP, the file managers are also unable to connect to your hosting account. We’re still trying to get in touch with iFastNet to get more information about this issue.
