Despite a last-minute critical update released by Parity before the weekend, the Ethereum mainnet upgrade of "Istanbul" was smooth and it looks like the entire network migrated together this time .

All of our services are operating as expected following the fork.

The next Ethereum network upgrade will be "Muir Glacier", which is due to happen at block 9,200,000 and scheduled to occur on Tue, Dec 31, 2019 around 8:35 AM.
