Destiny's beta may not be the only game affected by the PlayStation Network's connectivity issues. As a result of "high volume," likely due to today's Destiny beta launch on PS4 and PS3, the PlayStation Network is currently listed as "intermittently available." That basically means connection is spotty right now.
In response to the status, the official Twitter accounts of FIFA 14 and Battlefield 4 have posted warnings to fans:
We're currently investigating the connectivity issues affecting #FIFA14. Sorry for the inconvenience.

So far those are the only two games to report any possible issues, but it's nice to err on the side of caution.
