Long wait time for Googlesyndicate.com


I’ve been noticing my lazyloading images take a few extra seconds to actually load in if I quickly scroll down on my page. Looking at the waterfall, I see there’s a 2 second gap between loading in the final font and for a request to Googlesyndicate.com:

After this has been processed, the lazy loading images load in super quick.

Any idea what’s going on here and how I can mitigate / troubleshoot this?
