Hello,
when looking at the zoomed out map there is a strange "cutoff" in the USA on the very left side:

Link tho this map area:

Zooming in, it appears to be around longitude -118.
Where is this coming from?

That's the "big re-trialeration" effort we've been talking about on Twitter.
There are actually three of those bars moving through the northern hemisphere right now, cleaning up "smudges" where our old cluster-detection algorithm got confused.

for the others: check out North Africa and Europe (currently passing through Brussels), and North America starting after St. Louis, currently bumped up against Atlanta/Detroit, and passing Los Angeles (this one should start moving quickly after getting past San Diego because of the relatively sparse population density of the US/Canada in the rockies and much of the west. Look for big "slow-downs" at Mexico City, Phoenix, Denver, and a staying slow starting at San Antonio all the way to St. Louis.
Because we cache map tiles to keep from getting completely crushed, you'll see these in snapshots.
