Pretty normal yea, lots of people have reported Indian ISPs routing to Singapore. Routing isn't just about the closest place, Cloudflare controls which routes are available to who (which carrier, ix, etc) and ISP has the final control over where it is routed to. This isn't a Workers thing, but a general cdn thing

is there a way to restrict swaggerui dashboard access to only local environment? im using @Cloudflare/itty-router-openapi

ChaikaOP•4/3/24, 12:58 AM

that's not surpising, geolocation with anycast ips like CF is always wrong

Santosh•4/3/24, 12:58 AM

How do I know the real location? SFO seems irreasonable with that latency

ChaikaOP•4/3/24, 12:58 AM

That IP exists in more then one location (anycast) so it's hard to assign a single location to it

Santosh•4/3/24, 12:59 AM

Yes, Anycast it is!

SSantosh How do I know the real location? SFO seems irreasonable with that latency

In general, you can go to

/cdn-cgi/trace

/cdn-cgi/trace

path of your website, ex:

https://d1-a-ut.makemyparty.live/cdn-cgi/trace

https://d1-a-ut.makemyparty.live/cdn-cgi/trace

, and look at

colo={airportcode}

colo={airportcode}

, and that airport code is the identifider of the location you hit

ChaikaOP•4/3/24, 1:00 AM

Of course, you can't do that with most looking glasses, so you just have to guess by ping time or if traceroute or reverse dns exposes something obvious. Sometimes you'll see one of the end IPs be an Internet Exchange making it pretty obvious

Santosh•4/3/24, 1:01 AM

And I would have to do this from within India if I want to really locate that colo (in this particular case)

Santosh•4/3/24, 1:02 AM

Is there a cloudflare utility like thatof Vultr that allows me to trace it locally to a region?

ChaikaOP•4/3/24, 1:02 AM

for example:

ChaikaOP•4/3/24, 1:02 AM

if you google

38.10.0.47

38.10.0.47

, you get a peering db result, it's CF's IP for them on Extreme IX in Bangalore, so it's most likely going to Cf's Banglore colo

Santosh•4/3/24, 1:02 AM

gotcha!

ChaikaOP•4/3/24, 1:03 AM

should probably go to #off-topic or #general-help since this isn't workers related

az•4/3/24, 1:20 AM

if i am using durable objects for rate limiting should i use an alarm to delete buckets that are inactive?

dave•4/3/24, 1:25 AM

Is there a way I can have my Worker "push" data back so that the client doesn't disconnect?

dave•4/3/24, 1:32 AM

is there a 100,000 ms limit or something on a Worker?

James•4/3/24, 1:37 AM

100s is the default timeline for Cloudflare http things

dave•4/3/24, 1:41 AM

I increased the proxy timeout to 6000s; I thought that would apply?

dave•4/3/24, 3:27 AM

Is there no easy way to increase that?

Hi all, I'm building an API. I need to find some data from a relatively large file (1~3 GB). The file is encrypted, so I also need a functional algorithm to decode the data from the file. What data storage solution should I choose? Thank you.

Hello, is it possible to modify HTML of react site using cloudflare workers with HTMLRewriter?
If my understanding is correct cloudflare workers modify HTTP responses.
But on react site there is not a new HTTP request when page is loaded because react works by changing DOM content.
Any help and explanations would be greatly appreciated!

Hello, I’m Allie!•4/3/24, 8:51 AM

HTMLRewriter can only modify HTML that exists Server-Side. Generally, React uses a single div, that is then populated on the client side. So unless you can get React to do some of the work on the server, then no

Might be this?

If the system detects that a Worker is deadlocked on open connections — for example, if the Worker has pending connection attempts but has no in-progress reads or writes on the connections that it already has open — then the least-recently-used open connection will be canceled to unblock the Worker.

If the Worker later attempts to use a canceled connection, an exception will be thrown. These exceptions should rarely occur in practice, though, since it is uncommon for a Worker to open a connection that it does not have an immediate use for.

Otherwise, not sure what it could be

for context, what I'm doing, is shoving the same data into five R2 buckets in each region, and also pushing it into the Cache API (so I avoid a Class B completely in even more situations).
