Wondering why my update is not working

Sounds like you're not able to connect to our server rsync.macports.org.

It's working fine for me right now. Is it still not working for you?

Has it ever worked for you?

Does your network, or your computer via some network filtering or antivirus program, block access to rsync servers?
