If customers can't even do an nslookup on your server hostname, it sounds like a DNS problem, as opposed to blocking the server IP.
Of course if all the nameservers for your domain are on your IP block, then it could be they are blocking all your IPs. What specific response do you get from nslookup or dig? What happens if the customer temporarily sets their DNS server to something like 8.8.8.8 instead of Charter's resolvers? Does nslookup now work but still can't ping the server? Is it possible you are on a VPN server blacklist that Charter subscribes to? Although that would usually cause a different set of problems, like customer unable to access a service like Hulu, which doesn't want people watching via a suspected VPN service from a region where the content is not supposed to be available. -----Original Message----- From: AF <[email protected]> On Behalf Of Seth Mattinen Sent: Wednesday, May 22, 2019 6:29 PM To: [email protected] Subject: Re: [AFMUG] Charter blocking our billing Server On 5/22/19 4:25 PM, Dennis Burgess via AF wrote: > Call them.

They've become really stupid since they started calling themselves "spectrum". I had a multi day hard outage and NOC wouldn't ack it until the third day. So glad I kicked them to the curb after we got our Hurricane POP. -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
