Are any of the regular posters in this thread linked to RB World? Try unlinking and see if that improves connectivity at all. I'll follow up with Web / Live Ops to see if it's possible that this could be similar to the issue we saw yesterday.
There are no guarantees that it's the same issue but it would explain 1) why users in this thread reported an increase in problems around Blitz launch 2) why we wouldn't see these problems reflected in our server logs and 3) why Live Ops wouldn't have seen an issue that was more Web based. At the very least, it's worth trying to see if it points us in the right direction.
