Davao City Mayor Sara Duterte extended the enforcement of the Safe Davao QR to November 23 due to server crashes and registration errors caused by simultaneous access to the system.

The Philippine News Agency reported that “the city government decided to take down the site for maintenance due to high web traffic.” The major cause of traffic-related website crashes is a mismatch between the number of users coming to a website and the capacity of the site’s infrastructure to support this volume of visitors using the website simultaneously. Simply put, the sytem used by the city government could not match the number of people accessing the site at the same time. The influx was caused by the narrow gap between the announcement of the directive and the supposedly enforcement of the system.

“It came to the point that some 10,000 people register or access the site at the same time. So our IT team asked me if they can temporarily take down the site to stop the influx of thousands of people accessing (the site),” Mayor Sara said in a radio interview.

The Mayor also clarified that November 23 is not a deadline to register for DQR Code and that it is the new date where the enforcement of the Safe Davao QR will start. On that day, people out in the streets without their personal DQR code would be apprehended but people can still register for their personal DQR even after November 23.

Davao City residents like MB employee Alexander Velasco tried to register at around 2AM but failed because of a system crash due to influx of registrants. Gina Amora-Ocon of Barangay Dacudao in Calinan was able to start the registration process but the system failed and the page showed “There was an error loading barangay” the most common error registrants encounter.

In an interview with BNSHosting founder Wilson Chua, he said that in order to make the website functional despite of the number of people accessing it, two things should be considered. First, the need to increase the web server resources and second, the need to optimize the code. He further explained that people manning the system need to monitor the resources like memory, CPU utilization, bandwidth and disk usage then figure out which of these resources is causing the bottleneck. Upon knowing which, it is then a must to apply more resources and re-examine the code to reduce the demand on that offending resource.

Baguio City has the same problem with their contact tracing system but Mr. Chua’s team solved the problem by applying the same principle. “We solved this same problem with the contact tracing system of the city government of Baguio. We reached out to Davao City government to assist them with this, but so far no reply from them.” Mr. Chua said.

If you encounter errors, just check again to register and get your personal QR code.
