“Phishing” is a cyberattack that tricks users through fraudulent websites, emails, text messages, phone calls, and other communications. The attacker aims to persuade the user to reveal sensitive information, enter login credentials, or download malware. Phishing is a form of social engineering.
To troubleshoot and investigate a Support ticket in an efficient and effective manner, the WPVIP Support team needs to fully understand the scope, nature, and context of a request. If the initial request in a ticket does not provide sufficient information, the amount of time required to communicate and resolve the issue will increase.
The Geographical Redundancy feature enables an application to be fully restored and operational at an alternate data center with minimal downtime and data loss if the primary data center experiences a critical failure.
Slow queries are SQL database queries made by application code that take an unusually long time to execute. An increase in slow queries will reduce the efficiency and resiliency of an application’s database. A site with frequent slow queries might appear to operate well under normal amounts of traffic, but can perform poorly if the amount of traffic increases even by small amounts.
Notifications for organizations and Notifications for applications can be configured for a variety of event types. Event types include detected performance metrics anomalies, the success or failure of code deployments, and vulnerabilities detected by Codebase Manager in the plugins deployed to an environment.
Performance metrics anomalies are events that indicate a degradation in performance related to an environment’s object cache hit rate, slow queries, number of 5xx responses from the origin server, or the rate of 429 responses from the edge server—as measured against the known range of metrics for a performant application.
WordPress VIP supports PHP sessions for storing short-lived, ephemeral session data. Session data is backed by Memcached to improve performance, but to ensure a site’s stability and scalability the performance of its underlying code should be optimized wherever possible.
Direct access to an environment’s database is limited, but users can view data in a read-only phpMyAdmin console session or interact with the databases on WPVIP through WP-CLI commands run via VIP-CLI.
Enterprise Search can improve the performance of search results for a WordPress site and is highly customizable, however there are some limitations and default behaviors that cannot be overridden.
Redirects cannot be configured for any URLs that include /wp-content/uploads/*. The VIP File System, which resides upstream from application code, serves all files at that path. A reverse proxy is a possible solution for making a static asset available at a specific URL.
