@lap Cool, will give it a try, thanks for the suggestions!
If it helps, I switched to a Wufoo form integrated with my Mailchimp account, and am now able to process subscriptions again, so not sure whether it’s an issue on their end, or what’s up.
@lap nope, I’m on 4.5.3 – I’m using Media Temple’s managed WP hosting package.
I checked with MT, here’s their answer to me: The cURL version that comes with Premium WordPress is 7.45, and requests to *.api.mailchimp.com should not be blocked.
Here’s a screenshot of the error log:

Thanks for following up on this so quick!
Experiencing the same issue on my site: http://jasonamunwa.com/subscribe
It was functioning just fine yesterday, and I noticed today that the connection has been broken. Tried re-entering my Mailchimp API key, but it hasn’t made any difference. It also doesn’t provide any specific error message.
