Many have been waiting for Iron Banner since last week, specially for those that are missing the gear to level up and acquire better weapons and gear. According to Bungie
Destiny will be undergoing maintenance tomorrow 6/28/2016 starting at 8AM PDT. Expected completion is 2 PM PDT. https://t.co/Ocy0lEVMfq

We will have to wait for the undergoing maintenance to complete, which will take effect at 8 am PDT and expected to finish at 2 pm PDT.
Iron Banner will wait for you, Guardians. We have work to do before it can begin. https://t.co/apiNHlha41

We hope that all goes well and we are able to play in the activity and have enough time to level up and get the gear item that you are in need.
