Network Upgrades & Outages

The starting point for Network Upgrades & Outages is blockchain upgrade events, alongside hard fork coordination and network outage incidents. Relevant work examines validator software upgrades, chain halt investigations, and consensus failure recovery; service availability disruptions and upgrade compatibility risks help establish the outcome. The account reconstructs sequence, cause, impact, response, and recovery through network restart procedures, post-upgrade performance, and chain halt timelines. Evergreen network profiles belong under Blockchain Networks; this category requires a concrete upgrade, fork, degraded performance, halt, restart, compatibility issue, or service-restoration timeline.
