Summary
https://nicathletics.com is hosted by Presto Sports. Communications and Marketing manage this site and are the liaison to Presto for any technical issues. Since this site is hosted offsite, we are just responsible for verifying that name resolution is working correctly since we do manage the actual domain name.
Systems Involved
- nicns1.nic.edu
- nicns2.nic.edu
Overview
Presto Sports has published our website using the following hostname: ddbmt27ai79ls.cloudfront.net. This is globally load balanced by them into multiple AWS datacenters. We created a CNAME for www.nicathletics.com to point to this hostname. For the domain itself, we created A records for nicathletics.com to the IP addresses of the hosts that are returned when doing an nslookup of ddbmt27ai79ls.cloudfront.net.
For SSL/TLS, we also created a CNAME _28660994a788f9d7e76b20ed3aa8ffe8.nicathletics.com. that points to _fa9c1580037136d17afd03da6730ad1f.kzhndfqvzk.acm-validations.aws. which is required for AWS Certificate Manager (ACM).
Troubleshooting
If there are connectivity issues with nicathletics.com, we can determine if one or more of the hosts are having an issue. If there is an issue with that host(s), we can remove that A record from DNS and add it back when functionality is restored. To do this test:
Add the following records to your local hosts file. For Windows desktops, this is located under C:\Windows\System32\drivers\etc and you will have to edit this file as an Administrator
18.67.65.43 nicathletics.com
#18.67.65.83 nicathletics.com
#18.67.65.98 nicathletics.com
#18.67.65.118 nicathletics.com
#99.86.38.91 nicathletics.com
#99.86.38.20 nicathletics.com
#99.86.38.59 nicathletics.com
#99.86.38.65 nicathletics.com
Once these are added, you can save the file. Note that the first entry does not begin with a # - the # comments out that line so that the system does NOT use it. You can verify this by pinging nicathletics.com, your workstation should return 18.67.65.43. Launch a web browser in private mode and navigate to https://nicathletics.com. If the site loads, this host is functional. Edit the hosts file, comment out the first entry, uncomment the next entry, and save. Your workstation should resolve the uncommented address and check the https://nicathletics.com site again in a private browser.
If there are addresses that are not functioning, remove them from DNS
Checking to see if there are additional addresses that ddbmt27ai79ls.cloudfront.net resolves to:
Do a nslookup for ddbmt27ai79ls.cloudfront.net to see if there are additional addresses that might be hosting this site. If there are, validate that they are functioning and then add those Address records to DNS. Since this is an AWS hosted site, these addresses could change.
