Glory to the diesel engine!

This afternoon we received a letter quoted just below:

On April 7, from 9 am to 3 pm, scheduled work in the power supply network will be carried out in the data center of the Infobox company.

The unit will be installed in the area between the diesel generator set and uninterruptible power supply. The operating time of the uninterruptible power supply is designed for 20 minutes, so the data center will be de-energized for some time. As a result, during this period the work of websites, e-mail and other services will be suspended.

The employees of our company and the specialists of the equipment supplier company will carry out all the preparatory work in advance, which will minimize the downtime, which according to experts, can be 1-1.5 hours.

The installation of the ATS unit will fully automate the launch of a diesel generator set in case of problems with the supply of electricity to the data center.

Hope for understanding.
Sorry for any inconvenience.
