DNS bug in Cloudflare

[@debadipti]

It's crazy how technology works, such as DNS, so flawlessly which we have taken for granted

[@olorundaolaoluwa]

The challenge with this approach is that you have needless machines running, and you can rack up cost on running servers

[@arten8281]

Needless? I mean why would we scale up if we don't have users accessing it?

[@Sumitkumar-zw6wd]

Good work Mehul, sharing knowledge will motivate others to become like you

How do you handle SSL certificates (issue and renewal) in this case? When using free service lets encrypt, how will it validate each servers?

[@bhavyajain638]

Yes, using this should break the SSL certs. Maybe we use custom certs or something?

[@codedamn]

why not? for HTTP challenge for ssl cert your VPS is responsible for serving page (which is independent of A record IP), and for DNS challenge your TXT record is applicable (which is also independent of A record IPs)

We need more system level videos like this.

Keep going brother. Good work.

We did round robin routing not at digitalocean level but at nginx level on our master server. It really scales well. Its a bit tricky for websockets. For WS we have to do sticky routing preferably.

Its wonderful the way you do subtle promotion of fermion. It does not feels like promotion. Its like 99% pure knowledge and just 1% promotion. I am learning a lot from you @mehul. Will definitely try out for my aiinterview platform.

[@GameBully2K]

a cloudflare fintech engineer is writing a report about this feature rn. "We make it hard to load balance on the DNS so they go with the paid load balancer" hahaha

[@flekenstine3063]

1st view... on these Theo kind of videos...

[@engineeringwithai]

hmm, i have observed issues with paid also. but i have never been able to get to the bottom of the issues. interesting to discuss maybe how to debug these issues better?

[@Edw9n]

is this fixed now?

[@kartikkankurte717]

Why were there mixed colors ( green n blue) when it was not using http2, I would be less surprised to see that when using http2 though because it fetches response in segments through http streaming

What website you are using to draw these in your video ?

[@govindkaran]

[@debadipti]

it's really interesting

[@whatcd]

can u make a video? i have a few question cause i have very less knowledge in this, i use Firefox and safari, mostly i use Firefox with ublock add-on, thing is 1. certain websites i visit from google search, notification of spontaneously antivirus comes that it has blocked certain ip. cause website tried to access. 2. once there was some hidden malware installed on my laptop cause i visited website with antivirus ON, but still got infected and had to remove that malware by antimalware software, even not browsing i sued to get notification of antivirus that blocked the ip access. those ip i google it were some random chinese or some other place. 3. what happened in browser or pc background, how the script or website malware gets downloaded and run without our authorization?? 4. how to prevent that, i fear searching on google now.
