Strange error popup about 8 minutes ago

[seismic1]

I had the following message appear in an error popup about 8 minutes ago:-

"SyntaxError: Unexpected token '<', "<!DOCTYPE "... is not valid JSON"

A minute later I got a 522 error followed by a 523 error.

Site restart?

Those looks like Cloudflare error codes. Maybe a temporary "network blip" on their end. Also, quite possible that it was related to a site update as you suggested.

The errors were from Cloudflare.
