Adding a domain is refused with "Safety check unavailable"
What you are seeing
You try to add a custom domain and it is refused with "Safety check unavailable".
#Why it happens
Every domain name you add goes through an automated safety review. This time the review could not finish, perhaps because it timed out or the service was briefly down.
When that happens, we play it safe and block the domain rather than let it through unchecked. It is not a verdict on your domain. The check simply did not get an answer.
#What to do
Wait a few minutes and try adding the domain again. If it keeps happening, contact support.
