SQL Selezione da due tabelle con inner join e limit

Puoi farlo:

SELECT 
  ser.id, 
  ser.name, 
  s.status, 
  s.timestamp 
FROM Service ser 
INNER JOIN status as s ON s.service_id = ser.id
INNER JOIN
(
   SELECT
     service_id, 
     MAX(timestamp) AS MaxDate
   FROM status 
   GROUP BY service_id
) AS a  ON a.service_id = s.service_id 
       AND a.MaxDate = s.timestamp;

Il join con la sottoquery:

SELECT
  service_id, 
  MAX(timestamp) AS MaxDate
FROM status 
GROUP BY service_id

Eliminerà tutti gli stati tranne quello con l'ultima data.
