Atlassian says that this month's two-week-long cloud outage has impacted almost double the number of customers it initially estimated after learning of the incident.
As the company's Chief Technology Officer Sri Viswanath revealed on April 14th, nine days after the incident started, a maintenance script accidentally wiped hundreds of customer sites due to communication issues between two Atlassian teams working on deactivating a legacy app.
