Video conferencing service Zoom says it’s investigating the cause of outages that apparently affected some users’ ability to host and join in meetings. The outages on Sunday disrupted some churches that had previously shifted their weekly services online during the coronavirus pandemic. Several migrated to YouTube and Facebook or rescheduled services. The company said the problems seemed to affect a limited number of users. According to the website Downdetector, the problems appeared to have peaked around 5 a.m. Eastern time, with another spike around noon. The site tracks disruptions in tech services and collects reports. Zoom says it's assessing the situation and apologized for any inconvenience.
