DNS, CNAME and proper due diligence
Tags :Technical
So here is the scenario:
ACT 1
Place: Data Center with smiling sales
rep and customer
Customer has a server for some time
and adds a domain for web and mail as they merge with another company.
Following easy DNS we make a new DNS zone and create MX and A records
for the new domain. Wow, the world of the web and email is great
ACT 2
Place: Data Center and Customer Site
(flip back and forth) with smiling people
Customer goes for years with awesome
performance and no issues
ACT 3
Place: Customer site and Data Center
with people running around and banging on keyboards
Customer fails to renew one of their
original domains. This domain was used in the reference for the CNAME
and MX records for the merger. Suddenly mail and the website cannot
be found and no apparent reason. After much troubleshooting we tracked
it backwards and made the appropriate changes to get it back in line.
ACT 4
Place: Cubical with people with missing
hair in patches
Closing scene with customer.
Phone conference explaining to them that they let one of their original
domains expire. This in turn broke the other domains that referred
to it through CNAME and MX.
Writer summary: For gosh sakes check
your DNS tables and make sure you are current on domain registrations
