(UPDATE: As of 6:06pm, we were able to access our Canva account–but it may vary per user)
Several users of Visual Suite Canva (including us) could not access it today (November 12). We initially got an Error 503 before it started throwing Error 504 to us.
Downdetector also confirms that Canva is running into issues, and the majority of the complaints refer to being unable to access the website.
