Self-Service Portal Homepage Cache Issue on some US/EU Portals

Duration: ~2h55m. Cause: CDN cache contamination of homepage caches. Impact limited to US and EU Self-service portal homepages. All systems normal.

Self-Service Portal homepages are now returning correct content after cache purges. We are monitoring edge cache consistency and user reports for recurrence.

Root cause narrowed to CDN cache contamination triggered by a configuration rollback. The contamination affected homepage edge cache only.

Some customer Self-Service Portal homepages were showing other customers' homepage content. Other pages (search, article, product pages) remained functional. Workaround: avoid the homepage. Append a language code, or add a query character such as ?, to force a fresh render.
