Update
We expect the Istanbul fork for Mainnet to occur as scheduled at block 9069000, which we estimate to happen near 2019-12-08 0100 UTC. Infura backend systems for Mainnet are already upgraded and prepared for the Istanbul release, but as with any fork we will monitor our systems around the time of the fork for any potential issues.
