[outages] Can't reach 1.1.1.1 from AS12271, AS6453

[Nick Lopez]

I'm unable to ping or resolve DNS via 1.1.1.1 from a residential
Spectrum/TWC link this morning.

Some traceroutes:

Using Tata's AS6453 looking glass ( http://lg.as6453.net/lg/ ) from any NY
router seems to confirm trouble there:

Router: gin-njy-tcore3
