If you added a domain to Oribi, only to have it show up for a day and then disappear mysteriously, it could be because that domain hasn't received enough traffic and Oribi has marked it as a noise domain.

A domain needs at least 5 unique visitors in the last 30 days to appear in the domains list. The system checks every 24 hours for domain stats, so try visiting the domain in question several times in incognito mode, and then check back the next day to see if it's reappeared.
