Test and report public writeable status

Would be a nice attribute to add! So if a gateway is actually online, try writing some content as well to see if it's writable and report back status. Would love to see a PR for adding this :)

@victorb I created a similar tool that makes this, measure gateway latency, status code, etc, you can check it out here https://gateway.ipfs.io/ipfs/QmXHzertynCrRi9A99JH1fbxLATtGCaU4L3gkLo6ov9JEW

@fooock that is amazing. It is weird that it is not considering siderus.io as writable. How do you perform the check?

[fooock]

@koalalorenzo I make a post request to the gateway domain plus :5001/api/v0/add. For example, in siderus.io, the final post request will be https://siderus.io:5001/api/v0/add, if this request return success, then the node is writable, otherwise isn't. Do you see it correct?

[koalalorenzo]

No it is not correct since :5001 is exposing API. By definition in the settings a writable gateway basically allows POST methods. You should be able to check just that, right?

[fooock]

@koalalorenzo it is fixed now, can you check it and write some feedback in the referenced issue if needed?

@fooock Looks pretty good!

I've found that based on my VPN current exit point I have significantly different latency values. Could you guys perhaps add separate latency columns for US, Europe and Asia for example? Or a dropdown at the top of the page to select the testing location?

I often timeout with the default ipfs.io gateway and it would be great to know what gateways are working fast from where I'm trying to access IPFS from.

Edit:
Latency depending on the exit point while using ipfs.io to open an IPFS vs IPNS link:
US Florida: 511 ms vs 1.02 mins
Switzerland: 368 ms vs 1.01 mins
Japan: 775 ms vs 1.02 mins

So my presumption was wrong, because it was not the VPN's exit point, but the IPNS lookup that timed out my queries. Sorry about that!

@andrasfuchs yeah IPNS is crazy slow

FWIW the gateway checker here: https://ipfs.github.io/public-gateway-checker/ -- runs the checks on your local computer. So those latencies are from your current location and setup (e.g. w/ VPN vs without)

[andrasfuchs]

@jamiew Thanks, I didn't know that!

[jamiew]

This would be a nice add inside this repository too -- wonder if we could bundle requests more intelligently, so we're not just making 3 requests per server? That's not end of the world

Following up on some stale issues -- @fooock, are you interested in adding your writeable status feature into this repo's codebase?

[SgtPooki]

Looks like the code for fooock's implementation is in Java: https://github.com/fooock/ipfs-gateway-checker/search?q=writable

we should implement this feature but in js
