March 15, 2022 – Ocean carriers are scrambling to adjust their networks as the Chinese city of Shenzhen begins a week-long lockdown. According to a notice issued by the Shenzhen COVID-19 Prevention and Control Command Office, the city’s circa-17m residents must stay at home until Sunday – apart from going out for three rounds of testing – following which, “adjustments will be made according to the new situation.” Most carriers have yet to release advisories as “we don’t know what to say”, said one carrier source on March 14.
