While Zcash has not had any downtime, the blockchain's rapidly growing size has led to troubles for nodes' ability to sync with the network.
ZCash has a 2MB block size limit and blocks are found every 75 seconds (1.25 minutes), on average. That's more than 10X the current average block size for the bitcoin blockchain.

In August, Zcash researchers proposed a new fee mechanism that aimed to incorporate fees based on transaction size. In such a scenario, fee rates would keep increasing when the network is under extreme usage.
