What factors are contributing to the increased latency in Cato Networks's cloud-native firewall service across European points of presence?

Introduction

Increased latency in Cato Networks's cloud-native firewall service across European points of presence is a critical issue that demands immediate attention. This analysis will systematically identify, validate, and address the root cause while considering both short-term fixes and long-term strategic implications.

I'll approach this problem by first clarifying the context, then ruling out external factors before diving deep into the product ecosystem, metric breakdown, and data analysis. From there, I'll form hypotheses, conduct root cause analysis, and propose validation methods and solutions.

Clarifying Questions (3 minutes)

• Looking at the geographical scope, I'm thinking this might be a regional infrastructure issue. Could you confirm if this latency increase is uniform across all European points of presence or if it's more pronounced in specific locations?

Why it matters: This helps pinpoint whether it's a widespread issue or localized to certain areas. Expected answer: Varied impact across different locations. Impact on approach: If localized, we'd focus on specific POPs; if widespread, we'd look at broader network issues.

• Considering recent product updates, I'm wondering if there have been any significant changes to the firewall service in the past month. Have any new features or optimizations been rolled out recently?

Why it matters: Recent changes often correlate with performance issues. Expected answer: A list of recent updates or confirmation of no major changes. Impact on approach: If changes were made, we'd scrutinize those specific updates; if not, we'd look at gradual degradation factors.

• Thinking about user behavior, I'm curious about any shifts in traffic patterns. Has there been a notable increase in user traffic or changes in the types of applications being accessed through the firewall?

Why it matters: Unusual traffic patterns can strain resources and impact latency. Expected answer: Information on traffic volume and composition changes. Impact on approach: Significant changes would lead us to investigate capacity and optimization issues.

• Considering the nature of cloud services, I'm wondering about our current resource allocation. Can you share any recent changes in our cloud resource provisioning or autoscaling policies?

Why it matters: Inadequate resources can directly impact service performance. Expected answer: Details on resource allocation strategies and recent adjustments. Impact on approach: This would guide our investigation into potential resource constraints or misconfigurations.
