Checking Website Availability from Multiple Global Locations – An Expert Guide

Have you ever faced an issue accessing a website from your location for some reason while your friend abroad had no problems? As businesses expand reach across borders, increasingly more people are facing such availability challenges.

Website owners have to tackle various factors like servers going down, network congestion, varied regulations, device compatibility and more to ensure their online properties are available 24/7 for all visitors globally.

This comprehensive guide from a veteran test engineer will explain why worldwide availability matters, challenges teams face, how to smartly check availability across locations and expert tips to optimize access.

Why Consistent Website Availability Globally is Critical

In the modern digital era, for many businesses having a website that is consistently accessible and fast across the world can literally make or break operations. Consider these statistics:

• 53% of mobile visitors will abandon a website taking >3 seconds to load (Google)
• A 1 second delay leads to 7% loss in conversions for e-commerce sites

As you can see, speed and availability have a direct revenue impact. But the challenges don‘t end there.

Software teams have to ensure that their web applications work flawlessly when accessed from different countries via various devices, browsers and under realistic network conditions.

With online activity booming globally after the pandemic across sectors like software, retail, banking, entertainment and more – having 24/7 website access is now an expectation, not a nice-to-have.

Website availability refers to the percentage of total time a website is publicly accessible to visitors when they attempt accessing it. Industry benchmarks are:

• 99.95% uptime = low availability
• 99.99% uptime = moderate availability
• 99.999% uptime = high availability

Delivering "five 9s" uptime equaling 10 minutes of downtime per year is what leading enterprises target through extensive testing before launch.

Now let‘s examine key reasons why websites may be inaccessible across geographies and how you can check availability.

Main Factors Impacting International Website Availability

While planning to ensure your website is consistently available globally, these are the main technical and regional factors teams have to test for and optimize across locations:

Latency Caused by Distance from Servers

The greater the physical distance between visitors trying to access a website and the hosting web servers, the higher will be the latency which directly impacts page load times.

Solutions include using globally distributed CDN and hosting infrastructure to reduce delay by serving visitors traffic from edge locations closest to them.

Bandwidth Limitations in Developing Countries

Fast broadband connectivity cannot be taken for granted globally. Users in developing countries often suffer from very limited bandwidth availability resulting in painfully slow website loads.

Optimization techniques like selective content delivery, compressed resources, offline functionality help mitigate this.

Traffic Spikes Overwhelming Servers

Sudden traffic spikes beyond expected volumes from real users, bots or distributed attacks can overwhelm hosting servers and cause them to crash leading to worldwide outage.

Proactive capacity planning with buffer, auto-scaling serverless infrastructure easily handles demand spikes without downtime.

Varying Internet Quality and Speed Globally

Internet speed, stability and governance policies related to censorship, net neutrality etc. vary a lot across regions which directly impacts website availability.

Performance testing from within different countries combined with having local mirrors or caches help improve resilience.

Device and Browser Compatibility Issues

Cross-browser compatibility problems and mobile versus desktop experience inconsistencies can create device or location specific functional errors or performance lag.

Investing in comprehensive test automation across real viewer environments proactively catches issues before launch.

Domain and Hosting Related Downtimes

Even with robust web application code, downtimes caused due to domain registrar problems, shared hosting failures or cloud provider outages also impact availability.

Choosing highly reliable vendors, failover systems and real-time monitoring ensures early issue detection.

Impact of Internet Regulations on Website Access

Regional internet regulations related to data laws, censorship policies, sanctions etc. may intentionally or unintentionally throttle traffic or block access to websites from specific locations.

A geo-aware architecture and compliance reviews help minimize disruption.

Testing for and addressing these variables is key to delivering an optimized website globally.

How to Test and Monitor Website Availability Across Locations

Comprehensively testing and monitoring website availability for global users involves 3 main steps:

1. Determine Key User Locations and Prioritize Accordingly

Not all website visitors are equal when it comes to availability importance from business impact perspective. Prioritizing markets helps focus testing.

For example, for a travel site – testing website functionality from United States, Canada, UK, France, India, UAE, Singapore and Australia could be the priority.

2. Select Realistic Device Configurations for Each Location

Along with network locations, the device types and platforms visitors use also varies globally. Hence testing needs to address disproportionate mobile usage in Asia vs desktops in Europe for instance.

Browser selection also varies by region significantly. Safari leads in Oceania, Chrome in North America & Europe while UC Browser still dominates parts of Asia.

3. Set Up Functional Tests and Availability Monitoring

With locations and devices finalized, automated tests across required combinations uncover region-specific issues.

Scheduled availability monitoring from global networks 24/7 via uptime checks offers assurance. Alerts notify teams of potential problems.

Historical reports provide insight into issues over time across geographies while real-time dashboards indicate current status.

Pro Tip: Integrating monitoring systems with internal tools like Pingdom with PagerDuty allows reliable alerting and quicker issue resolution.

Expert-Recommended Best Practices for Improving Website Availability

Along with rigorous testing and monitoring processes, adopting the following technical measures greatly enhances worldwide website availability KPIs for online businesses:

Load Balancing Traffic Across Multiple Servers

Globally distributed website traffic is load balanced seamlessly across multiple servers in a cluster which handles demand spikes smoothly without downtime while improving response times.

Auto-Scaling Cloud Infrastructure Capacity

Scalable container-based cloud platforms like AWS and GCP easily auto-scale web application capacity vertically and horizontally to meet sudden traffic peaks preventing crashes.

Content Delivery Networks and Caching

CDNs store cached static website content like images, videos, CSS etc. on globally distributed edge servers closer to visitors which cuts latency tremendously.

Failover Systems With Real-Time Data Backups

Failover systems reduce the risk associated with hardware issues, data center failures etc. by quickly switching to redundant infrastructure with latest data backups so users don‘t notice downtime.

Optimizing Web Code Efficiency

Clean and optimized code, browser compatibility, adoption of web standards results in faster client-side processing, reduced server load and more responsive experiences for global website visitors.

Proactive Synthetic + Real User Monitoring

Leveraging both synthetic checks and viewer metrics offers comprehensive insights to catch errors before customers across regions notice degradations.

With a sound hosting strategy, automated testing procedures, and by following these tips any company can deliver 99.9%+ consistent website availability and performance globally.
