We've been observing a small about of intermittent packet loss to/from AT&T and Level3 here in the San Francisco Bay Area this morning. In examining the situation, it seems like a evenly-spaced dropping of packets to certain IPs.
We experienced similar issue last week off our level3 connection for a specific /21 customer block. After further troubleshooting we decided to re-route our /21 to the other provider where packet loss issue went away. We are still scratching our heads over this issue. regards, /virendra
This appears to end users like some IPs on destination networks are reachable, while some adjacent ones are not.
I suspect this is due to a failed LAG leg or ECMP leg on Level3's side.
We were able to route around the problem for now.
