California heatwaves deprived Twitter of a major data center and threaten its stability

Times are tough for Twitter, as Elon Musk scrambles to reverse the takeover of the social network. In California, extreme heat deprived the company of one of its main data centers located in Sacramento. A Twitter executive has warned that another simultaneous outage could shut down the service for some of its users, reveals CNNwho consulted an internal memo.

Why it matters. The outage occurred on Monday, September 5, in extreme weather conditions. This incident lends weight to the revelations of Peiter Zatko, former head of security at Twitter, who turned into a whistleblower. According to him, the social network does not have sufficient redundancy in its data centers, which consists of duplicating hosting on different sites in order to reduce the risk of failure in the event of a localized incident.

Peiter Zatko had denounced this risk in a document sent to the American authorities in July, and which CNN echoed. According to him, small failures that would occur in several data centers could cause the temporary shutdown of Twitter for several weeks or even months.
