Ever Given Suez Canal Blockage
The Ever Given Suez Canal Blockage was the March 2021 grounding of the container ship Ever Given across the Suez Canal, which halted traffic for six days and left hundreds of ships waiting.
What happened and why it matters
The Ever Given blockage made the risk of a single chokepoint visible to everyone, and it added weeks of delay to inventory already strained by the pandemic shipping crisis. The ship ran aground on March 23, 2021, and was refloated on March 29. More than 400 vessels queued at the canal's entrances, and the backlog was not cleared until April 3. Some carriers sent ships around Africa instead, adding about two weeks. Importers felt the effects as late arrivals, bunched vessel calls at European ports, and further container shortages. The event is a common example in contingency planning for lead time buffers.
