8. Oracle managed services failed to grasp what a replication timestamp was. For a week, their daily report was indicating that the replication had worked flawlessly even tho the timestamp on the target hadn't changed.
9. Oracle managed services sent me the daily report of another company, with financial information, on more than one occasion. They have also obviously sent my customer's data to other companies.
10. Back when Sun was still a separate entity, they won a 4 years staffing/project contract where the first action point was implementing unified authentication with LDAP (the site was mostly Solaris 8, with some HP-UX and a pair of AIX boxen). They only successfully delivered this feature 7 years later, after three contract extensions, when the whole site had been migrated to Solaris 10. They were surprised when they didn't win the new staffing/project contract and even more surprised when the customer massively migrated to RHEL.
