The Next-Day option means that Juniper Networks delivers advance replacements for defective hardware on the next business day for replacement requests placed by 3 p. m. local JTAC time, Monday through Friday, except Juniper Networks' regional holidays. For countries where Juniper Networks does not have an in-country depot and next-business-day delivery is unavailable, Juniper will ship the replacement part within 24 hours of the replacement authorization. Actual delivery will be subject to local customs and importation, restrictions, and transportation delays.
