On January 31, 2017, one of Gitlab’s software developers accidentally removed client's’ data from the primary database server. In addition, several backup attempts didn't work and the company lost access to a huge amount of data. Gitlab.com’s service was not available for 18 hours, which was unacceptable for the company. Just to stress the gravity of the issue, Gitlab’s clients are such companies as IBM, Sony, NASA, Alibaba, Invincea, Jülich Research Center, O’Reilly Media, Leibniz-Rechenzentrum (LRZ) and CERN, and it was their code that Gitlab accidentally deleted. The crisis started the moment Gitlab announced the issue through the social media.
