Resolving DNS Resolution Failures in Google Cloud Environments

by Anjali Sindhu
written by Anjali Sindhu

DNS (Domain Name System) is a critical component of modern cloud infrastructure. Applications, services, databases, and APIs rely on DNS to translate human-readable domain names into IP addresses. When DNS resolution fails, applications may become inaccessible, service communication can break, and users may experience significant downtime. In Google Cloud environments, DNS issues may result from incorrect DNS zone configurations, network misconfigurations, firewall restrictions, forwarding rule errors, or external service dependencies. Understanding how DNS works within Google Cloud and following a structured troubleshooting approach can help administrators quickly identify and resolve these problems. Understanding DNS in Google Cloud Google Cloud provides DNS services through Cloud DNS, a scalable and highly available managed DNS platform. Cloud DNS supports both public and private …

Resolving Disk Performance Bottlenecks in Compute Engine

by Anjali Sindhu
written by Anjali Sindhu

Disk performance plays a critical role in the overall responsiveness and stability of applications running on Compute Engine. Even when CPU and memory resources appear healthy, storage-related constraints can cause slow application response times, increased latency, database delays, and reduced throughput. Identifying and resolving disk performance bottlenecks is therefore an essential part of maintaining reliable cloud infrastructure. This article explores common causes of disk performance issues in Compute Engine, methods for identifying bottlenecks, and practical techniques for improving storage performance. Understanding Disk Performance in Compute Engine Compute Engine offers multiple storage options designed for different workload requirements. Persistent Disks and Hyperdisk volumes provide varying levels of performance based on factors such as disk type, provisioned capacity, and workload characteristics. Disk …

Spot VMs vs Standard VMs in Google Cloud

by Anjali Sindhu
written by Anjali Sindhu

Virtual machines (VMs) form the basis of a great many cloud applications since they provide the computing resources required for efficiently running workloads. Google Cloud provides several VM options via Google Compute Engine, among which Spot VMs and Standard VMs are the two most frequently used. Even though both types of VMs serve the same basic function- running applications in a virtualized environment- they are designed to meet different operational requirements, with standard VMs emphasizing reliability and continuous availability, whereas spot VMs concentrate on cost savings for workloads that can tolerate interruptions. It is essential to understand the differences between these two options if you are to build a cloud infrastructure that achieves a balance between performance, availability, and cost. …

Page Cache vs Buffer Cache: What’s Actually Happening

by Anjali Sindhu
written by Anjali Sindhu

You would have come across page cache and buffer cache, whether or not you were aware of it- if at any time you checked the memory usage on a Linux server and saw a large amount of RAM listed as “cached” or “buff/cache”. They are more than simple consumers of memory; in fact, they are active mechanisms for performance optimization which have been incorporated into the Linux kernel. Their purpose is to reduce disk I/O, improve application response times, and make good use of available memory. Yet the distinction between page cache and buffer cache often causes confusion even among experienced Linux administrators and system engineers. If you understand how these caching mechanisms work, you will be able to troubleshoot …

How to Detect and Fix CVE-2026-58047 Before Attackers Strike

by SupportPRO Admin
written by SupportPRO Admin

Security issues that target hosting control panels can cause problems because these panels often manage many websites, email services and user accounts from one place. A recent issue is CVE-2026-58047 a problem that affects cpsrvd the web service that handles requests to cPanel and WHM interfaces. The problem is part of a group called HTTP Request Smuggling. This does not mean a server is definitely broken. It gives attackers a way to change how web requests are seen by different parts of the system. If the issue remains unresolved, this vulnerability could expose hosting setups to potential risks.

Exim Security Alert: GCVE-25-2026-07-45-3 Explained and How to Fix It

by SupportPRO Admin
written by SupportPRO Admin

Email infrastructure is a critical part of modern IT environments, supporting everything from customer communication and password resets to automated system notifications. Exim, one of the most widely used Mail Transfer Agents (MTAs), powers email delivery for countless Linux servers and hosting platforms. Because of its widespread adoption, security vulnerabilities affecting Exim deserve immediate attention from system administrators. One such issue is GCVE-25-2026-07-45-3, a recently disclosed vulnerability involving Exim’s handling of .forward files under specific configurations. Unlike vulnerabilities that can be exploited remotely, this issue is classified as a local privilege escalation, meaning an attacker must already have access to a local user account before attempting exploitation. While this limits the attack surface, affected systems should still be patched promptly …

Common AWS Security Group Mistakes That Block Traffic

by Anjali Sindhu
written by Anjali Sindhu

One of the most common reasons an application becomes inaccessible on Amazon Web Services (AWS) is a misconfigured security group. Your EC2 instance might be running well, your application could be healthy, and your load balancer might be functioning correctly, but users still cannot connect. Often, the issue lies with a simple security group rule that is missing, incorrect, or too restrictive. AWS Security Groups are like virtual firewalls that control the traffic coming in and going out of your AWS resources. While they aim to improve security, even a small mistake in their setup can block legitimate traffic, causing website downtime, failed application connections, or inaccessible services. In this blog, we’ll explain what AWS Security Groups are, discuss the …
