Intermittent Application Access Issues - (July 8, 2025)

Duration: 1 hour 35 minutes (3:25 AM - 5:00 AM MDT)
Affected Services: All ProLink Solutions web applications
Status: Resolved

What Happened

On July 8, 2025, beginning at approximately 3:25 AM MDT, users experienced intermittent access issues across all ProLink Solutions web applications. During this time, customers may have encountered 504 Gateway errors, partially loaded pages, or been temporarily unable to connect to services. The issues affected sites randomly, with some working while others were unavailable, then alternating.

Our monitoring systems detected the anomaly immediately and alerted our engineering team, who responded within minutes to investigate and resolve the issue.

Impact

The outage caused intermittent access problems for all ProLink Solutions web applications during overnight hours. We recognize that many of our customers operate around the clock, and we sincerely apologize for any disruption this caused to your operations.

Resolution

Our engineering team identified that our security systems were responding to malicious traffic patterns by temporarily blocking connections to protect our infrastructure. While this was the intended protective behavior, it inadvertently affected legitimate user traffic as well.

The team adjusted security configurations to restore full service by 5:00 AM MDT. All systems returned to normal operation, and we continued monitoring closely to ensure stability. The malicious activity ceased shortly after resolution.

Root Cause

Analysis of our system logs revealed that our infrastructure was targeted by an external security threat originating from overseas. Our security systems correctly detected the malicious activity and attempted to protect our services by temporarily blocking suspicious traffic patterns.

However, due to the nature of the attack and how it was routed through our infrastructure, the security response also temporarily affected legitimate user connections, causing the intermittent 504 errors customers experienced.

Important Security Note: This incident involved automated scanning activity attempting to identify potential vulnerabilities in our environment. At no point was any customer data accessed, compromised, or at risk. The attacker did not gain access to our applications, databases, or any customer information. Our security systems functioned as designed by detecting and blocking the malicious activity. The service disruption was solely the result of our protective measures temporarily affecting legitimate traffic while defending against the threat.

Our Response

We are committed to maintaining both the security and availability of our services. In response to this incident, we are:

• Enhancing our security configurations to better distinguish between malicious and legitimate traffic
• Implementing additional geographic and network-based protections to prevent similar attacks
• Working with our security vendor to refine threat detection rules and response mechanisms
• Reviewing our security alerting to ensure faster identification of false-positive scenarios

We appreciate your patience during this incident. The security and reliability of our services remain our top priorities. If you have any questions or concerns, please contact our support team.
