cURL error when loggin in from sites, and hub updates unsuccessfull

hi there,

my membership lapsed for like 3 days before renewing.
upon renewal, i get this error from the site mentioned in where i'm trying to log in:

Your server had a problem connecting to WPMU DEV: "HTTP Error: 403 "Forbidden"". Please try again.

If this problem continues, please contact your host with this error message and ask:

"Is php on my server properly configured to be able to contact with a POST HTTP request via fsockopen or CURL?"
also, when trying to run updates from the hub to any other site, they literally all fail.
please will you check on your side? i've left it for about 20-odd hours to see if that makes a difference, but it didn't.

pretty keen to get installing and updating plugins again....
