Good Evening All
Thank you all for reporting this to us. I have forwarded this to our team to ensure it gets looked at as soon as possible.
I will post here when I know more, however as it is the weekend, it may take a little time for our team to be able to look into this. There is no maintenance scheduled on our servers, and it appears that the servers are either experiencing issues, or currently have too many connections (based on the error message shown in the FTP logs, linked to earlier).
Regards
