Where I work petro points is a partner.
We use one of their online APIs at retail.petro-canada.ca
Let me show you something
Date: Thu Jun 6 14:37:46 UTC 2019
Basic:
$ dig retail.petro-canada.ca +short 156.44.144.39
Name servers?
$ dig petro-canada.ca NS +short dns1.cidc.telus.com. dns2.cidc.telus.com. secondary-ns1.allstream.com. secondary-ns2.allstream.com.
Interesting: two large Canadian providers doing DNS for this domain. From time to time issues arise because not all name server have the same information. Let check that:
$ for i in `dig petro-canada.ca NS +short`; do echo $i; dig @$i retail.petro-canada.ca +short; done secondary-ns1.allstream.com. ; <<>> DiG 9.10.3-P4-Ubuntu <<>> @secondary-ns1.allstream.com. retail.petro-canada.ca +short ; (1 server found) ;; global options: +cmd ;; connection timed out; no servers could be reached secondary-ns2.allstream.com. 156.44.144.39 dns1.cidc.telus.com. 156.44.144.39 dns2.cidc.telus.com. 156.44.144.39
I think found a problem.
I think there is no NS record for secondary-ns2.allstream.com. Dig more.
Also let do a whois to se how many of the name servers in the NS record are in the whois record, do they match?
$ whois petro-canada.ca ... Name Server: dns1.cidc.telus.com Name Server: dns2.cidc.telus.com Name Server: ns1.business.allstream.net Name Server: ns2.business.allstream.net ...
So that looks good. Awesome to see them using DNS across providers, this will hopefully protect again failures.
Allstream and Telus are competitors.
Alltream owned by Zayo, which bought integra, now watch the trace on the allstream name server:

So why can't I get a NS recorf for allstream.com ? I'll ask both integra name servers:

OK now what ?
ned to call allstream which might be integra online .
