For web-application monitoring, we’ve [1] gone the approach of outside-in monitoring. There’s many approaches to monitoring and depending on your role in a team, you might care more about the individual health of each server, or the application as a whole, independent of its underlying (virtual) hardware.

For web applications for instance, we care about uptime & performance, tls certificates, dns changes, crawled broken links/mixed content & seo/lighthouse metrics.

Damnit, they found my loop-hole! https://ma.ttias.be/loophole-cookie-notices/


"Geeks don't have interests, they have passions."

I live by this.


What do you mean you live by this? Do you mean you make a conscious choice to have passion instead of an interest? I don't think one can choose a passion. It's something you either have or don't.


Hey! Sorry to hijack the thread for the other, but just like the OP we've spent the last few years building Oh Dear and it does about 99% of what you're looking for. [1]

It has uptime, performance, SSL alerts and status pages. What's missing is the performance graphs on the status page, which is coming in a few months.

Simple Ops goes further than us by also measuring FCP though.

FYI you may want to remove the reference to HipChat from your landing page.


One point I don't see made often: in order to short or long any market, you need _initial_ capital too. This whole "ask 1 BTC to get 2 BTC" requires 0 initial upfront costs from the attacker.

It's a win/win situation, they can't lose. They've invested nothing in their scam to begin with.


Not just any initial capital, clean US dollars in a brokerage account under somebody's real name. You can't use BTC or rubles or drug money or whatever.


I hope everyone reads the post and not just the subject, which is misleading.

The tl;dr is: Microsoft will stop building the .exe's themselves, but PHP will still happily run on Windows. The community will most likely step in and build those binaries themselves.

For the common user, nothing much will likely change. They'll still be able to download the binaries straight of php.net, someone else will just have built them instead of Microsoft.


Hi Jake! Enter your website URL in here, and it'll tell you if you're affected or not: https://ohdear.app/tools/certificate


Here's a very quick way to check if you may be affected: this will check all certificates in the chain to see if they match the fingerprint of the to-be-revoked list.

Shameless plug, but I built a monitoring solution with extensive SSL checks that’ll catch & report these if they’re revoked: https://ohdear.app


This looks nice, I've recently started using instatus.com for the status page, but love your monitoring parts, might use the trial to further check it out!


Does this RFC just sherlock DNS Spy?
