Less than half of Ethereum nodes ready for upcoming Istanbul hard fork
Only 41.2% of nodes are ready for the Istanbul hard fork, which will take place on the Ethereum network at block # 9,069,000 approximately December 7:
The best results are shown by the popular Parity client, in which 45% of nodes were updated, in Geth those 40%. In good readiness, mining pools and services providing the Ethereum infrastructure (wallets, block browsers) - almost all large sites have prepared for Istanbul. But cryptocurrency exchanges are in no hurry, and at the time of writing, only the not-so-famous Bitso exchange has updated its site.
