Parity Technologies has announced a fix to a vulnerability in their Ethereum node implementation that was causing their nodes to go offline.
The fix is out—please update your nodes ASAP. https://t.co/t2bJLNuyZV
While the vulnerability only directly affects Parity Ethereum nodes that serve JSONRPC as a public service (e.g., Infura, MEW, MyCrypto, etc), we recommend everyone to update their nodes immediately.

The issue was discovered on February 3rd when Parity Tech received several reports that attackers were able to send a specially-crafted RPC request to public Parity Ethereum nodes.
The bug had opened up an attack vector to allow nodes to be forced offline by potential attackers. If undiscovered, the attack could have threatened a sizeable portion of the Ethereum infrastructure.
It would appear that the only affected nodes were the ones synced up to the JSON-RPC public services like Infura, MyEtherWallet, and MyCrypto.
The team has since released a fix and encourages all Parity node operators to update to the latest upgrade.
