Cloudflare/Internet2 Peering Outage?

Any Cloudflare contacts lurking? We observed a spike in DNS timeouts beginning around 7:20 PM EST. We eventually determined that DNS queries to Cloudflare-managed DNS servers, traversing our Internet2 connection, were consistently failing. Cloudflare servers reachable via our Cogent internet connection were fine. We applied a band-aid by shutting down our Internet2 connection, at which point all queries began to flow properly again via our Cogent connection We'll continue investigating in the morning, but might need assistance from Cloudflare. Thanks, Norman Elton William & Mary (wm.edu, AS 11975)
