Several readers have noted a strange error message appearing when trying to perform software updates from the Mac App Store.
An Error has occurred
The certificate for this server is invalid. You might be connecting to a server that is pretending to be "swscan.apple.com" which could put you confidential information at risk.
Swscan.apple.com is one of several servers that Software Update uses to communicate with Apple. The apparent problem is that the security certificate for the server appears to have expired. The certificate was originally valid from May 22, 2012 to May 24, 2014.
This is a problem that Apple will need to fix on their side. In the meanwhile, users can manually download updates from Apple's support site.
Update: This may also be the cause of NSURLErrorDomain error -1012, which appears to have started in the same time.
Update 2: Apple appears to have fixed the certificate.

Apple today announced a new subscription initiative that turns paid iCloud+ subscriptions into a broader services bundle in more than 100 countries.
In select countries, Apple says every paid iCloud+ plan, including the cheapest 50GB tier, now includes Apple TV and Apple Arcade "at no additional cost," while family sharing extends the storage, TV and Arcade access to up to five people....
Steve would have never let the Mac App Store become Snappier without the Heartbleed update render leaking, Tim.
Did I catch everything?
You forgot:
Microsoft Forgets to Renew... = Yet another example of a top-heavy corporation unable to keep even simple things in check. Thank goodness Apple hasn't forgotten its user base.
Apple Forgets to Renew... = Calm down, people; non-issue. Do you even realize how much time a big company needs to address things like this?
Apple needs to design an app where people can jot down a list of things they need to remember, with an option to add alerts when they become due. Could call it Reminders or something similar.
