Sadly, that's not a joke.

There are multiple news articles repeating the IRGC claim of a successful attack. Some have pictures of missiles and Oracle buildings. Most of the same building stock shots, including some of Oracle HQ in San Mateo, CA.[1]

There are also denials from the UAE press office calling this "fake news".

Oracle doesn't seem to have said anything. It's not even clear that they have a major data center in Dubai. They have two in Saudi Arabia (Riydah and Jeddah), but the Oracle status page lists none in Dubai.[2] They have some offices in Dubai, all on upper floors of buildings and probably not large data centers. Do press reports indicate a call to the Dubai office? (Phone: 971(4)3909000) [3] Nah.

I am not sure how to navigate this world any more.
