I would be interested in a severity score or something similar -- otherwise I can't judge how important it is to fix -- is this a "friday right now" problem or a monday is fine problem ;)

maybe I missed that, but why not just combine ptp and ntp within chrony, it does support that.

I think a very short lived cert (like 7 days) could be a problem on renewal errors/failures that don't self correct but need manual intervention. What will let's encrypt be like with 7day certs? Will it renew them every day(6

yeah, that was my suspicion as well, seems that AI generated content is mixed with seo-spam or malware. I even tried to report feedback.azure.com as a deceptive site to the major browsers, but they don't share my concerns ;)

I think Microsoft has a general problem with getting rid of unwanted things within their eco-system. I keep complaining that their feedback.azure.com portal is filled with spam/malware comments and links, but even internally their team

I have a Framework 13 (12th Gen). I have no complaints about the hardware quality. I love the replace everything concept. I rarely do that though, my ports are always the same - 2x usb-c, 1x usb-a, nic (bulky I remove that one for traveling

they do talk about actual usage in the talk, but only vcpu wise, not instance wise. For vcpus it's also more than 60% linux

by klaas- 2y ago
the actual talk (video in article) says more than 60% of VM vcpus are from linux VMs, it does not talk about instances though. But I would expect Linux to be a lot of very small and very large VMs :)

so the "real" azure nodes are some kind of special Windows+HyperV but for example their accelerator cards are linuxes: https://cfp.all-systems-go.io/media/all-systems-go-2023/subm...

you can use azure files nfs, that should be posix compliant, but it comes without auth or encryption ... :)

I also have a follow up to this topic. I would say it looks like in Azure nobody is verifying TCP checksums. A bitflip in tcp payload should have been noticed at the NIC/tcp level but it reaches my application with corrupted data.

after a full day of searching for a possible cause, someone from microsoft suggested that they try to move the express route gateways (which are seemingly VMs inside of Azure) to a different hypervisor. For now it seems like the first gatew

by klaas- 3y ago
so my guess would be there are more than a few devices between the edge and the express route gateway (which is more or less a VM I was told). So I am guessing right now someone is trying to figure out what hardware is involved in between t

yeah, that's what we did. We captured it at the last place in our network (a router) and then compared the tcp payloads to the packets that we received in azure in our firewall. Next step was to get the dumps from as much inbetween as

by klaas- 3y ago
So it seems this is their software defined network, the packets still look good when entering via the microsoft edge routers and they get bitflips on their way into our express route
