Parity issues emergency patch ahead of Ethereum Istanbul upgrade, questioned by community members

News on December 9th, the upgrade of Ethereum Istanbul was successful, but it was not all smooth sailing. All major clients released a version compatible with the upgrade in advance. Failure to upgrade will result in incompatibility with the latest version of the network. Parity released an emergency patch version for EIP1344 three days before the mainnet upgrade. Podcast host @AnselLinder said that only 41% of the nodes were upgraded 34 hours before the upgrade. "The problem with Parity yesterday caused its nodes (the number of update synchronizations) to become zero." Parity's mistakes have sparked criticism from community members.
