We are continuing to see elevated packet loss from a site in our GRU region to other fly regions in the US, via some US ISPs. Impacted apps may see degraded or broken connections. Local GRU traffic is unaffected. We are working with our provider in GRU to improve routing and will update once a fix is in place.
