Server usually have 2 power supply feed to 2 Distribution Board coming from 2 separate power source.
When power source trip, the other power source should be able to keep the server alive.
Server will also normally supported by UPS (Uninterruptible Power Supply).
In a Data Centre, backup power generator will kick in.
A server in the Data Centre - will normally not affected by power supply failure - unless the Power Grid from the Power Station trip - for a Tier 3 Data Centre Runtime Institute.
Even when a Power Grid trip, the UPS will sustain the Data Centre equipment for at least 20 to 30 minutes for the backup power generator to kick-in and take over the power supply from the Power Grid.
This is a basic standard requirement of a Tier 3 Data Centre Runtime Institute.
You mean hacker hack the power supply and trip the circuit breaker of the Distribution Board?
Unlikely.
Electrical cables are separate from IT cables unlike powerline.
Electrical System so far are not IT driven - especially for Data Centre - thus no way hackers can hack into electrical system to trip the circuit breaker.

When a hacker hacked a website, he/she would want to publicize it to make a statement. Screenshots will be taken and spread on the Internet. So far, we heard of none for this case. So I don't think there's any half truth.

Even if circuit breaker is
hacked and cause it to trip, with power source diversity - the 2nd Distribution
Board will be able to provide power to support the server.
Also UPS will support and take over the power supply for 20 to 30 minutes for backup power generator to kick in if both Distribution Board trip - causing no downtime to the Data Center server.
Thus server or Data Centre downtime due to power disruption can usually be avoided in a Tier 3 graded Data Centre under the Runtime Institute - where such redundancy and resilliency need to be built in - in order to be certified as Tier 3 Data Centre.

I am very surprised. Power trip? Even SME has a uninterrupted power supply and it doesn't cost much. I am not buying the claim....

UPS not good enough, it can only last for 20 to 30 minutes
depending on the number of battery.
In fact if UPS with network interface and SNMP are used,
it will trigger to shutdown the server gracefully before the 20 minutes to 30
minutes end - so that the harddisk of the server will not crash or operating
systems or files or
database in the server will not get corrupted - due to sudden cut-off of power
supply.
An E-source (Emergency
source) power supply need to kick in when UPS take over the power supply from
the main power source - else disruption of services is guaranteed as the server
will shutdown trigger by the network UPS and downtime will be a CERTAINTY.
