FTP Connection/Instantiation Hangs Application

Question

I am attempting to open a connection via FTP using the following simple code. But the code is just hanging at this line. Its not advancing, its not throwing any exceptions or errors. My code is 6 months old and I've been able to use this code to connect to my website and download files all this time. Today its just started to hang when I go to open a FTP connection.

Do you know what could be going wrong?

ftp = ftplib.FTP("www.mySite.com")  # hangs on this line
print("Im alive") # Never get printed out
ftp.login(username, password)

I administer the website with a couple of other people but we haven't changed anything.

Edit: Just tried to FTP in using Filezilla with the same username and password and it failed. The output was:

Status: Resolving address of www.mySite.com
Status: Connecting to IPADDRESS...
Status: Connection established, waiting for welcome message...
Error: Connection timed out
Error: Could not connect to server
Status: Waiting to retry...

Looks like you have server issues, but if you'd like the Python program to error out instead of waiting forever for the server, you can specify a timeout kwarg to ftplib.FTP. From the docs (https://docs.python.org/2/library/ftplib.html#ftplib.FTP)

class ftplib.FTP([host[, user[, passwd[, acct[, timeout]]]]])

Return a new instance of the FTP class. When host is given, the method call connect(host) is made. When user is given, additionally the method call login(user, passwd, acct) is made (where passwd and acct default to the empty string when not given). The optional timeout parameter specifies a timeout in seconds for blocking operations like the connection attempt (if is not specified, the global default timeout setting will be used).

Changed in version 2.6: timeout was added.
