Wp-calypso: Sites do not load when clicking 'My Sites'

[pauloeaquino]

A user is reporting that when they click on ‘My Sites’, nothing ever loads, therefore preventing access to any of their sites. It continues to display ‘Loading my sites’. I was able to confirm this after using SU on the user’s account.

Ticket: 816070-zen

Steps to reproduce

1. SU into the user's dashboard.
2. Click 'My sites'

What I expected

I expected the user's sites to be displayed properly.

What happened instead

Nothing loads. It continues to display 'Loading my sites'.

@pauloeaquino, any chance you can include OS/browser details for both the reporter as well as from your testing? Any time there's something funny going on with page loading, it's good basic troubleshooting to rule out a browser issue. See https://en.support.wordpress.com/browser-issues/ for a good place to start.

@designsimply, sure, here are my details from testing:
OS: macOS High Sierra 10.13.1
Browser: Chrome 62.0.3202.94 | 1258 x 564

The user said they tried three different browsers and right now we're currently waiting for their reply to provide their specific browser info.

My best guess for this one is a temporary outage (could be in fetching data over the API, so network connection). Most likely resolved on its own and not a specific bug in Calypso.

Feel free to re-open if you see a larger pattern (many people reporting it).
