Subject [jira] [Created] (INFRA-15822) Invalid DNS entries for www.openoffice.org
Date Tue, 09 Jan 2018 15:27:00 GMT
Andrea Pescetti created INFRA-15822:
---------------------------------------

             Summary: Invalid DNS entries for www.openoffice.org
                 Key: INFRA-15822
                 URL: https://issues.apache.org/jira/browse/INFRA-15822
             Project: Infrastructure
          Issue Type: Bug
          Components: DNS
            Reporter: Andrea Pescetti


As reported by multiple project volunteers (mostly from Europe) in the last 20 days, the http://www.openoffice.org
site and related sites like http://it.openoffice.org are intermittently unreachable.

After long investigations on the project's dev list, this seems due to broken DNS records:
out of two IPs supplied for www.openoffice.org, one is broken and the other one works.

Details:

$ dig www.openoffice.org
[...]
;; ANSWER SECTION:
www.openoffice.org.    165    IN    A    88.198.26.2
www.openoffice.org.    165    IN    A    140.211.11.105

The bad one is the first.
