This repository is a curated list of significant software failures and security incidents, and the missing case is the 2020 SolarWinds supply-chain compromise. It is a canonical example of how a trusted software update path can be abused to distribute malware across thousands of downstream organizations.

• Added the SolarWinds Supply Chain Attack (2020) entry to the English README in the same format as the existing outage and incident entries.
• Added the Turkish translation so the project remains consistent across both language versions.
• Included a concise summary, a direct quote, and supporting references to the official incident context and analysis.
• Kept the wording aligned with the repository’s existing tone and editorial style.
