I compiled a summary of the report published by NSCSC. However, I found that the report remained rather basic and there weren’t many learnings for me.

web-performance.ch web tools
Debugging the internet or services on the internet can be a challenging task. I regularly need to perform debugging lookups for performance or security. I review lists of IP addresses after defending against attacks on a web property. All of these use cases need specialized tools. Here is a collection of tools I like and use.

What i learned about Grok AI
As someone very interested in OpenAI’s ChatGPT, I wanted to test Grok. Currently, it’s only accessible to verified users of Twitter (aka X). It is possible to become verified with the Premium program, but it’s not that urgent for me.
This blog post started in November 2023 and now in February 2025 it continues. Finally, Grok is simple to test for everyone, and Grok-3 seems to be around the corner, challenging OpenAI, Anthropic, and DeepSeek with their latest model that now took the No. 1 rank on the current leaderboard. This increases the pressure for the other competitors to follow suit.
We deploy from Azure DevOps YAML pipelines to Azure App Services. We use msdeploy packages for this. In calendar week 45 of 2023, we discovered issues in our deployment pipeline. The pipeline started failing unexpectedly in various places.
The error message “ERROR_USER_NOT_AUTHORIZED_FOR_DEPLOYMENTPROVIDER” and details “Could not complete an operation with the specified provider (dbDacFx) when connecting using the Web Management Service.” were not very comprehensive for me, especially because it stopped working suddenly from one day to the next. Additionally, most of the linked help articles mainly relate to IIS.
This is the error we found in our pipelines in full.
##[error]Error: Error Code: ERROR_USER_NOT_AUTHORIZED_FOR_DEPLOYMENTPROVIDER
More Information: Could not complete an operation with the specified provider ("dbDacFx") when connecting using the Web
Management Service. This can occur if the server administrator has not authorized the user for this operation. dbDacFx

PHP Cron Push Monitoring
I run a cron job every 5 minutes to execute background processes. Once they have successfully completed, I execute the following PHP function to verify their success and measure the execution time. If the execution fails, it sends me a push notification indicating that the push/heartbeat was not received within the expected timeframe. I monitor the push timeframes on statuscake.com.

There are many tools available, but not all are for the same purpose. I will collect here what I tend to use and build know-how on.

SuperBenchmarker for Loadtest
SuperBenchmarker is similar to Apache Benchmark (ab.exe). It will display both ongoing real-time updates as well as a final result in HTML and on the command line. It can be easily installed with Chocolatey.
With the ability to parameterize SuperBenchmarker, it’s a quick and simple way to run a test right from your machine.
