Response status by service

MJS e-Document Cloud

Response status
Still suspended; reopening time unknown
Response information checked
2026-10-27

Current re-audit: Official response verified · Research date: 2026-10-27

Accounting, tax and business management systems.

The October27 18:10 service notice replaces the previous October28 00:00 reopening estimate with an unknown date. All functions, including APIs, remain stopped during safety checks.

Scope: The service notice cites external-software vulnerabilities. The corporate notice includes other vulnerabilities, so the cause is not attributed solely to the PHP CVEs.

What users should do

Documents registered in the accounting system during the outage remain in its accounting data. Re-registration instructions will be announced after restoration. Retry failed uploads and references after service resumes.

2026-10-27

Current re-audit: Official response verified · Research date: 2026-10-27

The October27 corporate notice still lists this site as stopped; an older scheduled end time in the individual notice does not establish recovery.

Scope: Applies to the licence site, not the entire application. The corporate notice covers other vulnerabilities too; the exact cause is not inferred.

What users should do

Contact MJS about licensing problems and follow the latest reopening notice.
