That sure stops in a hurry. What hardware are you using? Some routers use or block 1.1.1.1

Thank you for reporting the issue. We are looking into this

I reached out to Comcast in my area yesterday and it took them a few hours to get the information to the right person, but looks like they are blocking 1.1.1.1 at one(maybe more) of their Cable Modem Termination Systems since previously 1.1.1.1 was used as a testing address by some hardware/software. They told me it would be a few days before it was allowed again.

I have Comcast as well (Minnesota, USA). I also use my own modem, and a couple of AirPort Time Capsules. I tried to change the DNS server addresses on the one connected to the modem, and when it tried rebooting, I just got an amber light on the front. When I disconnected it from power, and restarted it, it booted back up with the DNS server addresses that were on it previously. Perhaps this is related?

@denike Comcast claim the issue is fixed. I m not sure about the cable modem thing. But please give it another shot and let us know if it is resolved.


#9

I spoke with Comcast yesterday and they have resolved the issue on this. Thanks case can be closed!
