Leap Second Crashes Big Websites

 

Were some of your favourite websites down on June 30th? Popular Internet sites such as Reddit.com, and LinkedIn were down on Saturday due to complications with the “leap second.”

A “leap second” is the insertion of an additional second into the Universal Coordinated Time (UTC) to keep the time of day as close to mean solar time. As UTC is used to coordinate servers worldwide, this additional second put Linux and Java users at a disadvantage.

Many systems were impacted by the problem. Mozilla reported Saturday issues with services using the Java platform. “Java is choking on leap second,” reported Mozilla engineer Eric Ziegenhorn in the companies bug reporting system. “We believe this is related to the leap second happening tonight because it happened at midnight GMT.”

Other websites reported issues through their social media channels such as Twitter. “We are having some Java/Cassandra issues related to the leap second at 5pm PST. We're working as quickly as we can to restore service,” tweeted Reddit.com.

“Some of you may have experienced difficulty accessing the site. Our team is working on it now. Stay tuned for more,” tweeted LinkedIn.

On the other hand, Google reported no issues, stating it had prepared for the “leap second” previously.

Fortunately services on all accounts were reinstated quickly, with only a few hours of downtime reported on certain sites. Next time, you can only assume, websites have learned from their mistakes and will be more prepared for the UTC’s “leap second”.

Intelliwave SiteSense boosts APTIM material tracking

Intelliwave Technologies outlines how it provides data and visibility benefits for APTIM

“We’ve been engaged with the APTIM team since early 2019 providing SiteSense, our mobile construction SaaS solution, for their maintenance and construction projects, allowing them to track materials and equipment, and manage inventory.

We have been working with the APTIM team to standardize material tracking processes and procedures, ultimately with the goal of reducing the amount of time  spent looking for materials. Industry studies show that better management of materials can lead to a 16% increase in craft labour productivity.

Everyone knows construction is one of the oldest industries but it’s one of the least tech driven comparatively. About 95% of Engineering and Construction data captured goes unused, 13% of working hours are spent looking for data and around 30% of companies have applications that don’t integrate. 

With APTIM, we’re looking at early risk detection, through predictive analysis and forecasting of material constraints, integrating with the ecosystem of software platforms and reporting on real-time data with a ‘field-first’ focus – through initiatives like the Digital Foreman. The APTIM team has seen great wins in the field, utilising bar-code technology, to check in thousands of material items quickly compared to manual methods.

There are three key areas when it comes to successful Materials Management in the software sector – culture, technology, and vendor engagement.

Given the state of world affairs, access to data needs to be off site via the cloud to support remote working conditions, providing a ‘single source of truth’ accessed by many parties; the tech sector is always growing, so companies need faster and more reliable access to this cloud data; digital supply chain initiatives engage vendors a lot earlier in the process to drive collaboration and to engage with their clients, which gives more assurance as there is more emphasis on automating data capture. 

It’s been a challenging period with the pandemic, particularly for the supply chain. Look what happened in the Suez Canal – things can suddenly impact material costs and availability, and you really have to be more efficient to survive and succeed. Virtual system access can solve some issues and you need to look at data access in a wider net.

Solving problems comes down to better visibility, and proactively solving issues with vendors and enabling construction teams to execute their work. The biggest cause of delays is not being able to provide teams with what they need.

On average 2% of materials are lost or re-ordered, which only factors in the material cost, what is not captured is the duplicated effort of procurement, vendor and shipping costs, all of which have an environmental impact.

As things start to stabilise, APTIM continues to utilize SiteSense to boost efficiencies and solve productivity issues proactively. Integrating with 3D/4D modelling is just the precipice of what we can do. Access to data can help you firm up bids to win work, to make better cost estimates, and AI and ML are the next phase, providing an eco-system of tools.

A key focus for Intelliwave and APTIM is to increase the availability of data, whether it’s creating a data warehouse for visualisations or increasing integrations to provide additional value. We want to move to a more of an enterprise usage phase – up to now it’s been project based – so more people can access data in real time.
