@lpallard:
Seems to be fixed now, I added the top domain to the Custom Whitelist but instead of adding the domain manually like
".githubusercontent.com"
I clicked on the + sign on the alert page, and the following domains were added:
.githubusercontent.com
.github.map.fastly.net # CNAME for (raw.githubusercontent.com)
I think the problem was that ".github.map.fastly.net" needed to be added as well. Now its working.
Yes Whitelisting from the Alerts tab is the best, as it will automatically whitelist any CNAMES…
You can still whitelist manually, but you should check for CNAMES... You could use a command as follows to find them:
drill example.com @8.8.8.8
