Just Europe/Oslo, or is Cloudlare down across the planet?

We are seing this on our sites, and having trouble loging in to cloudflare dashboards, getting Internal Server Error there as well.

Sandbox performance

Is it normal to have Sandbox cold starts take 2-5 seconds? Is there a plan to make this 10-100x faster?

[Please help CloudFlare staff] After deleting my account, only my community account remains.

I have a question. Is there a way to contact the CloudFlare community management? I previously canceled my account, but it's still there. I created a new account and tried to log in, but I couldn't log in as a different account. It doesn't have to be community support, but could someone from CloudFlare staff please respond?...

Cloudflare R2 - Assets not loading, returning 304

lazy-loaded chunks of react app causing issues on new worker deployments

We’re running into an issue with lazy-loaded chunks in our React app. After deploying a new Cloudflare Worker, if a user still has the old version of the site open and then navigates to a lazily loaded route, they get an error: “Failed to fetch dynamically imported module: …/assets/…” With CloudFront, we used to fix this by running an invalidation so users always received the latest assets. Is there an equivalent mechanism for cache invalidation or forcing clients to load the newest version when using Cloudflare Workers?...

Error DNS_PROBE_FINISHED_NXDOMAIN

Hello, good day. I wanted to ask for your support because my domain is not working with tunnels. It seems to be a DNS error, as if the domain were not registered, but I already purchased it directly through Cloudflare.

Discrepency in Vectorize and D1

Has anyone experienced a vector count mismatch with LangChain + Cloudflare Vectorize? I'm noticing a discrepancy where my D1 document count doesn't match my Vectorize index. For example, I have 12 raw documents in D1, but 48 vectors in Vectorize (4x the amount). Also I am seeing this discrepency in other indices where the vectors are 4x the raw chunks in D1. Have others run into this issue? Any insights on what might be causing this would be appreciated!...

Cloudflare says "Invalid Nameservers"

It's been almost 2 weeks since I changed the nameservers, but on cloudflare side, it says that it hasn't been changed. I checked on multiple domain information checkers (e.g. domain.hu) that what is the nameservers and it shows the right nameservers. I already clicked on "Check nameservers now" multiple times. Domain: zerra.hu...

DKIM

Has anyone seen this issue before? I've created a TXT record for a domin. The DKIM TXT record is not being recognized by email validators, despite being configured correctly in Cloudflare. The record is split into two quoted strings in DNS, which may cause compatibility issues with DKIM validation. Suspected Cause:...

Hosting a minecraft server

Hey, I purchased a domain through Cloudflare and I'm looking to host a minecraft server through it. Since my ISP uses CGNAT, I cannot open ports to the public, so I thought Cloudflare Tunnel would be a good choice, but I can't get that to work with minecraft communicating through TCP (from what I've found). I'd like some help on how to setup this server for me and my couple friends, where I start the server locally and my friends just connect through the URL.
