RE: DNS Hijacking? - FiOS Northeast

We are seeing DNS requests for A and AAAA to 8.8.8.8 come back with erroneous replies resolving to 146.112.61.106 
when sent via FiOS circuits in the northeast. Anyone else seeing issues with DNS on FiOS in Northeast? Issue started 
around 12:25 AM ET this morning and seems to be affecting customers in PA, RI, etc.. 

146.112.61.106 appears to be an Anycast IP served by OpenDNS when pages are blocked by the Cisco Umbrella service -

Are you sure the queries are going to Google 8.8.8.8 and not OpenDNS?

What URL(s) are you seeing this on?

Do you have a traceroute to 8.8.8.8 from an affected site?
