Icons that sometimes get discovered and sometimes don't

Why is that?

Is there a reason sometimes icon associated with the site does not get discovered? Example: Twitter
Moreover, why would sometime detail view icon differ from summary view? Example: Reddit

Hi @iwonder3,

The image service that we source icons from have to grab the icons from the sites themselves. It scans the site for the Apple Touch Icon first and then the favicon if it can't find anything. The problem is that, sometime the image service is overloaded, or the site itself is overloaded, times out and we can't get the new icon. We try again on the next day, so that we don't overload the site either.

As for the two separate views, the icon sizes are different in both views. The detail icon is bigger than the smaller icon in the item listing. We store at least three different sizes of each icon on our image service. The reason is that those can also be used in the iOS app where retina/non-retain images can be offered. It avoids the app having to rescale each time it downloads an icon, which eats up the CPU. So we do those calculations one time on our image service and the apps are smart enough to pull a specific icon it needs.

We're investigating a bug where we have the icon for a site but for some reason, the image service did not generate all the sizes, it has 32x32 pixel but not 64x64 or 128x128 sizes. That's why you can see the icon in the detail view but not in the item listing, or vis versa.

I can confirm we have 32/64 for Twitter but not 128. Reddit looks good here, can you confirm it's working now?

Thank you for responding. Here is what's happening with Reddit

Twitter looks ok (consistent)

Hi @iwonder3,

That looks right, that's how Reddit set it up with the sizes.
