Google has issued an apology for a significant disruption to its cloud services, acknowledging that the incident stemmed from an unusual update to the cloud platform's quota system. Multiple layers of flaws in the update process exacerbated the issue, resulting in the outage lasting for several hours. According to the incident report, over 70 Google cloud services worldwide were impacted last Thursday, encompassing both Google's own products like Gmail and third-party services such as Cloudflare and OpenAI. Google has pledged to enhance its systems to ensure that such incidents do not recur.
