We just moved from DHL Asia to Singapore Post since DHL is discontinuing services in Singapore for an indeterminate amount of time. We had to change our API as a result of this modification. Tracking websites are not receiving updates for the new Singapore Post tracking. Please visit http://tracking.linexsolutions.com/ manual tracking information. Within the following days, tracking will be available on websites such as 17track.net and tracking.buyetizolam.com
