What is https://internet-measurement.com/ ? It keeps requesting to my worker on different ports like 8443, 8880 and 2086
Nwell you can read maybe 
AHow do I block them?
Cthere's tons of companies and projects which scan the entire web and ip space, not particularly harmful,espec not to a worker which isn't going to be vuln to anything
Cif you want to try to block those, disable your workers.dev for that worker and use Custom Domains/Routes to bind your worker to your domain, and you can use a rule like
not cf.edge.server_port in {80 443}why 
AMy workers send me a discord message in some cases, it’s a bit annoying to receive messages when I didn’t call them
Nyou will always get some random requests
Sif (request.cf && request.cf.botManagement) {
const verifiedBot = request.cf.botManagement.verifiedBot;
if (verifiedBot) {
return fetch(request);
const verifiedBot = request.cf.botManagement.verifiedBot;
if (verifiedBot) {
return fetch(request);
Sdoes it work like that ??? does it work for busniess plan ???
SIs there a way to rate limit the worker such that requests that are rate limited d onot count towards the request limit?
WSI just checked and I dont find request.cf.botManagement on cloudflare worker , should I get specific bundle from cloudflare to get it
Jhas anyone written a worker based redirect / rewrite / proxy with configuration similar to netlify's _redirects?
JI'm imagining it would also support bound services
Jotherwise I'll try and scrape something together myself..
BHello, i am new, how is add domain and how update file??

Band can use laravel yes?
HWorkers(Unbound isn't really a thing anymore), while not a dedicated "heavy-compute" solution, gives you 30 seconds of CPU Time for HTTP(S) requests
Fhey! in my pages proejct i'd like to add some extra workers. how can i put them into a subdirectory with their own wrangler.toml and deploy?

II managed to bring this down to
"Service bindings are fast. When you use Service Bindings, there is zero overhead or added latency. By default, both Workers run on the same thread of the same Cloudflare server."
And all the RPC call does is read a environment variable. Curious if anyone has any insight into this?

HHow are you testing the speed?
ITime.now before and after the RPC call and log tail that pushes it to a log aggregator (axiom)
HAre you doing any other work before that point?
NI was following the Cloudflare Workers KV quick start guide and ran into an unavoidable error:
✘ [ERROR] Error processing request: TypeError: Cannot read properties of undefined (reading 'put')
I have no idea what this error means, and there aren't any docs or resources available to help.

LHi, I want to make websocket server for a game in worker. What does "Max of 30 seconds of CPU time per invocation" or "10 milliseconds of CPU time per invocation" mean? Does my websocket stops if it go over?
NHey @Mike Nomitch | Workers PM regarding your recent message on the announcement channels about containers in the workers platform, we have a very specific use case that is currently being delegated to fly.io which basically consists of the execution of long running tasks in an asynchronous manner, think of it as a job runner that can run a container instance to completion with parameters passed as environment variables.
We basically use it as a way of executing bulk Tasks like post processing on media, AI tasks, report generation, RPAs, puppeteer and other such things where system dependencies are needed.
Our main reason for delegating it to fly.io right now is that they don't impose a time limit so our long running tasks don't get timeouts while still providing quick startup times once the image is cached.
We find that currently no cloud provider provides a complete solution for running asynchronous jobs while just paying for the compute time and providing fast startups (we achieved that with fly.io but it required us to hack around with their platform API and writing our own scheduler) so I think that would add great value to the Cloudflare developer platform.

EHello guys I need help with cloudflare worker
as I was using K6 Gafana to load-test my worker.
It was went well at the start but then at certain time I cant sent request anymore. I'm not sure wether its the problem from K6 or Cloudflare worker that block repetitive coming request with in short period of time.
if the problem is with my Cloudflare worker, how can I unlock this block feature to test how much can my Cloudflare worker can handle? do I have to upgrade the plan or Are there any better solution to solve this
thank you
ps. I attatched the report file from my K6 to see whats the actual problem.
