Hi, for Cloudflare Dashboard is not working for some reason, is there a downtime or sth?

x03•3/26/24, 4:31 PM

I'm still a little nervous about the Cloudflare pricing though, its very possible that my initial app launch could cost a lot, since I cant really estimate usage at the moment.

x03•3/26/24, 4:31 PM

But I guess I'll see. Worst case scenario I can take the app down for a bit and switch to hosting on a VPS. I'd rather avoid that but if pricing becomes an issue that's the only choice I see as viable.

Yeah mine's down too

x03•3/26/24, 4:32 PM

for certain pages

Iiamnotapipe this website is tripping me out. what exactly is it supposed to be telling me??

Chaika•3/26/24, 4:33 PM

click on a dc and you'll see where DOs run

Iiamnotapipe this website is tripping me out. what exactly is it supposed to be telling me??

Chaika•3/26/24, 4:33 PM

for example, DOs in South America run in East Coast https://where.durableobjects.live/colo/GRU/

Where Durable Objects Live

São Paulo, Brazil(colo) | Where Durable Objects Live

Tracking where Durable Objects are created, wherever you are in the world.

x03•3/26/24, 4:35 PM

@Chaika this is kind of a broad question, but do you know of any tools that can estimate the cost of cloudflare services based on my expected daily users? Or anything similar to that

x03•3/26/24, 4:36 PM

I could do calculations by hand, but I'm not sure how to estimate certain things, like how many requests does a user send on average

x03•3/26/24, 4:37 PM

I guess I could actually just use the app myself like a normal user would, and tally up my requests that way

Iiamnotapipe what does it mean for a DO to "run"? i am not so sure how DO works .. is there a...

Chaika•3/26/24, 4:39 PM

Workers are V8 Isolates, a kind of single-threaded web environment javascript execution environment. Durable Objects are the same, also isolates, but the catch is there's only one per Durable Object ID in the entire world, and they have transactional consistent storage. Their storage has to be reliable, so they can only run in locations where there is several nearby DCs to replicate writes to

Chaika•3/26/24, 4:41 PM

Same region yea

Chaika•3/26/24, 4:41 PM

might fallover to a nearby dc but it won't go that far

Chaika•3/26/24, 4:41 PM

D1 DBs for example use DO Instances

Iiamnotapipe is a DO like a "singleton" that moves around??

Chaika•3/26/24, 4:45 PM

It doesn't move around, it stays in the same place once created.
You define a Durable Object in your code, for example for a session store. You then create a DO instance per user which gets created nearby and won't move, and you can save the session cookie/token in storage. Then, whenever the user goes to auth, you have the DO which is nearby to check for their auth. state.

jersey•3/26/24, 4:46 PM

cloudflare down? new domains not recognizing ;c

Chaika•3/26/24, 4:46 PM

You benefit from the fact that there's only one DO and storage is transactional/with locks, don't have to wait for eventual consistency like with KV, and it's nearby the user so low latency

Jjersey cloudflare down? new domains not recognizing ;c

Chaika•3/26/24, 4:46 PM

There is a current incident: https://www.cloudflarestatus.com/incidents/b31dxdz60366
You mean you added a new site, changed nameservers, and nothing yet? Would wait a while then, until incident is over

and now hours and still nothing

Chaika•3/26/24, 4:48 PM

You create a DO with a name and fetch it (or you can use random IDs, same idea though), like

    let id = env.MY_DURABLE_OBJECT.idFromName("us-west-player");

    let stub = env.MY_DURABLE_OBJECT.get(id);

    let response = await stub.fetch(request);

    let id = env.MY_DURABLE_OBJECT.idFromName("us-west-player");

    let stub = env.MY_DURABLE_OBJECT.get(id);

    let response = await stub.fetch(request);

That instance has its own storage and is created closest to the requester.

x03•3/26/24, 4:48 PM

A quick question. If my sessions NEVER change after being created, would it be better to just stick with BetterKV and cache sessions permanently or should I still switch to D1?

x03•3/26/24, 4:48 PM

If a user agent or IP changes, I log the user out and require the creation of a new session

Jjersey yep, normally domain recognizes within 10 minutes

Chaika•3/26/24, 4:48 PM

What's the domain? It could be related to that incident which has been going on for 2 hours but could check it over anyway just to be sure nothing obvious is wrong

Iiamnotapipe thanks for juggling all these convos at once. when you fetch the DO, will it mov...

Chaika•3/26/24, 4:50 PM

They never move. So if it was created before in us-west, it would stay there. If it's a brand new DO (identified by name/id), it would be created closest to the requestor. You can pass it in a region hint too. They'd be copies of the same code yea, but with their own storage/location/memory/etc.
In some languages/concepts they're basically "actors".
You could create a Durable Object per game server, everyone connects and it fans out game messages/keeps game state. You could do it per session. Cloudflare uses Durable Objects per region to fan out Single URL Cache Purges, etc. Little instances of compute with storage that are globally consistent.

jersey•3/26/24, 4:50 PM

i got multiple domains, on whois nameservers are on the domains and everything seems fine, and it just happened like within this 2 hours, pretty sure its because the incident. friend also same problem

Chaika•3/26/24, 4:54 PM

Yea, probably related if it's just within the last few hours.
I would just double check dnssec isn't the problem, and that you're not presetting the nameservers at your registrar before adding the domain. Cloudflare recently added it so if you preset the nameservers at your Registrar to your account's defaults, it will pick two new ones when you add it. As long as they're equal to the ones you see in your Cloudflare dash for that website you're good though.

CChaika Yea, probably related if it's just within the last few hours. I would just doubl...

jersey•3/26/24, 4:57 PM

the nameservers are equal, putting the domain first in cloudflare and then i copy the nameservers and put it in the registrar

jersey•3/26/24, 4:58 PM

also checked on whois, registrar and cloudflare, nameservers all are equal

jersey•3/26/24, 4:58 PM

and match the one on cloudflare

Chaika•3/26/24, 4:58 PM

Sounds good then! Yea, will just have to wait for that incident to be resolved and CF's ns checking to be back up, and should get an email about it being activated.

jersey•3/26/24, 4:59 PM

alright thanks! haha sorry for making this channel sort of support channel

Isaac McFadyen•3/26/24, 4:59 PM

Caching is never permanent, even with BetterKV.

Jjersey alright thanks! haha sorry for making this channel sort of support channel

Chaika•3/26/24, 4:59 PM

nah you're fine that's what this channel is for, products which don't have an explicit channel for them

Isaac McFadyen•3/26/24, 4:59 PM

The cache is a best-effort basis and is only valid for the same datacenter where it was cached.

Isaac McFadyen•3/26/24, 5:00 PM

That behavior is probably fine for you, since if you're checking on every request a user is likely to hit the same DC every request and so will hit the cache.

Iiamnotapipe thanks i will look into it a bit more and see if i can understand that where dur...

Chaika•3/26/24, 5:01 PM

It's just showing in which datacenter the Durable Object will end up in, if the user hits the one you've selected. colo = colocation, renting space in an existing DC, which roughly equals datacenter yea.
The dotted lines go to the place where the DO would be created.

x03•3/26/24, 5:01 PM

Makes sense. I guess I'll just stick with BetterKV until I swap over to D1 + cron jobs

x03•3/26/24, 5:02 PM

Are there any other caching / optimization tools that I can use with D1 or KV that could potentially save money?

x03•3/26/24, 5:02 PM

Besides doing rate limiting and designing the app in an efficient way
