Downtime (DOW)

Connectivity issues leading to reduced rewards.

Downtime Risks:

ID	Risk Group	Risk Vectors	Risk Vector Description
DOW1	Infrastructure	External: Operational Failure of Cloud Service Provider	Cloud Downtime, malfunction
DOW2	Infrastructure	Operational Failure of own bare metal set-up due to malfunction software	Malfunction of software (e.g. validator client or third party software) leads to downtime
DOW3	Infrastructure	Operational Failure of own bare metal set-up due to malfunction hardware	Malfunction of hardware (e.g. physical network, computer system, CPU, RAM) leads to downtime
DOW4	Infrastructure	External: Operational Failure of own bare metal set-up due to people (ManMade)	Employees are responsible for the downtime event (accidentally or intentionally)
DOW5	Infrastructure	External: Operational Failure of own bare metal set-up due to natural causes	A natural event (e.g. earthquake, flood, hurricane,...) leads to an downtime
DOW6	Infrastructure	Failure to design for high availability	Having too few beacon nodes relative to validator clients, leading to: - opportunity costs - slashing on some networks
DOW7	Infrastructure	External: Internet connectivity	Loss of infrastructure network connection due to: - Sudden cloud outage - Sudden internet failure in on-premise machines - Accidental firewall change locks out access.
DOW8	Infrastructure	External: Power supply	Power Breakdown
DOW9	Infrastructure	External: Power supply	Volatile power supply damages infrastructure
DOW10	Infrastructure	External: DDOS attack	Systems unresponsive, slowed down, and compromized due to buffer/stack overflow
DOW11	Software	Software Bug in the Validator Client	Downtime or accidental interpretation of dishonest behavior
DOW12	Software	Software Bug in the Validator Client (Intentional or accidental) through software update	New versions of a validator client that may cause errors that lead to downtime (Supply chain attack)
DOW13	Software	Software Bug in the Validator Client through software customization	New versions of a validator client may cause errors that lead to downtime
DOW14	Software	Software Bug in third party software	Third party software failure can lead to downtime of the whole system
DOW15	Software	Latency / Failure of relays	Latency / Failure of relays
DOW16	People	Malicious Internal Employee (intentionally causes operational failure)	An employee having too privileged access
DOW17	People	Malicious Ex-Employee intentionally causes a downtime incident	A Ex-Employee can still have access to the system when his acces is not blocked or removed
DOW18	People	Malicious External Hacker (intentionally causes operational failure)	A hacker may find a way to overload the system or shut parts of it down manually.
DOW19	Software	Running outdated validator software	The node operator os not updating its validator software
DOW20	Software	Validator client update incompatible with IT system	System downtime after validator client update caused by incompatibility
