Oh Dear

Oh Dear monitors your entire website, not just the homepage: uptime, SSL, DNS, cron jobs, broken links, performance and status pages.

[Oh Dear @OhDearApp]

Shipped this week:

Four free tools (a cron expression editor, an SSL certificate checker, a redirect checker and DNS watch), clearer wording on passing certificate checks, and an empty state for status pages without monitors. 🔥

Update: we're still seeing 2.1x as many sites being down as our normal baseline, not every site has been brought back online yet 👀

[Oh Dear @OhDearApp]

These last 24hrs have been interesting in PHP land, to say the least! Here's everything we saw, from a monitoring perspective.

At its peak, 18.8% of all sites we monitor were down 😱

[Oh Dear @OhDearApp]

Where we could safely detect it, we sent out e-mail alerts to team owners if we detected their monitors were still running old/unpatched PHP versions 💪

Stay safe out there folks - patch asap! 🙏

[Oh Dear @OhDearApp]

You can read more about these in our blog, with some more commentary & interactive charts to see more data visualisation on these last 24hrs ⬇️

We'll update the post in a few hours again to see how the tail-end evolves and if those sites recover 🤞

For the servers that answered with an HTTP/503, the majority was behind Cloudflare.

In hindsight, that might have been unnecessary. Cloudflare was very fast to deploy mitigation via their WAF rules for all customers, but at the time, we couldn't have known for sure. Safety first!

[Oh Dear @OhDearApp]

Our systems are patched & the website + dashboard are available again.

[Oh Dear @OhDearApp]

Out of caution, we've taken our website & dashboard offline, until the official PHP patches come out.

All your monitors continue to run in the background & you'll still be alerted.

Stay safe out there, fellow PHP sites 🖖

@mozexdev We'll be back ASAP!

Out this week:

Simpler first monitor setup, webhooks that fail for 48 hours now pause themselves, scoped API tokens locked out of team-wide endpoints, stricter email verification, and a bunch of fixes, including missed scheduled task pings. 🔥

[m@ttias ⚡️ @mattiasgeniar]

Small UX improvement to @ohdearapp: our MCP path at /mcp now shows a quick placeholder with instructions, if you come via a browser https://t.co/grPzrgsHnT

For most projects, that's just a broken link (unless used via a coding agent), feels like an easy win 👀

[Oh Dear @OhDearApp]

New week, new changelog.

Configurable check frequency for Application Health, stronger SSRF protection on uptime and AI checks, task details in late scheduled task webhooks, and a bunch of server errors turned into proper validation messages. 🔥

[Oh Dear @OhDearApp]

Latest changelog is out.

Up to 90 days of uptime history on status pages, custom status page icon colors, uptime check intervals up to 24 hours, a fix for abandoned status page CNAMEs, and a bunch of fixes. 🔥
