So yesterday, for a few hours, Windows 7 users were not able to use the community site for a couple of hours due to certain browsers being unable to use a more modern, more secure SSL encryption algorithm.
Very quickly, @bko and @peekay123 (at community.spark.io) alerted us that they were having problems, and we reverted it—thanks for letting us know so quickly!
This incident was caused when we were in the process of rotating our SSL certificates in response to the HeartBleed bug. Note that we patched all of our systems within 24 hours of the initial announcement; SSL certificate rotation is an additional mitigation measure we're taking.
In the coming days we'll be finishing this process. We'll be sure to update this status page if any issues arise.
