Hello hackers,

Please take a look at the January report on buildfarm failures:
# SELECT br, COUNT(*) FROM failures WHERE dt >= '2026-01-01' AND
  dt < '2026-02-01' GROUP BY br;

# SELECT COUNT(*) FROM (SELECT DISTINCT issue_link FROM failures WHERE
  dt >= '2026-01-01' AND dt < '2026-02-01');

# SELECT issue_link, COUNT(*) FROM failures WHERE dt >= '2026-01-01' AND
