Know When a Site
Goes Down Before
Your Client Does

On any paid plan, every site you connect to mySites.guru gets an uptime monitor that checks it every 5 minutes and tells you when it goes down and when it comes back.

Watch an outage reach your channel

Every site is checked every 5 minutes. After three failed checks the alert goes to Slack, Discord or Teams, and the same channel says so when the site is back. More short films.

Transcript

Your client's site went down at 3am. Who found out first? Too often, it's the client, on the phone at nine.

Meet Uptime Monitoring, in mySites.guru. Every site you add is checked every 5 minutes. Paste one webhook URL, and alerts go to Slack, Discord or Teams.

If a site fails three checks running, your team's channel knows straight away. If the check times out, it tells you the host is almost certainly blocking our monitor, with a message ready to send to the host.

When the site answers again, the same channel says so. So you call the client before they call you. Uptime Monitoring. In mySites.guru.

Three attempts before we call it down

A single failed request is often a blip: a busy PHP worker, a slow database query, a host restarting a service. So one failure does not trigger an alert. The monitor tries three times, 10 seconds apart, and only a 2xx status counts as up.

Every check comes from one published address, 165.227.239.229. If your host or a firewall challenges unfamiliar traffic, allowlist that one IP and the checks get through.

  1. 1

    HEAD request

    45 second timeout. A 2xx status means the site is up and the check ends here.

  2. 2

    HEAD again, 10 seconds later

    Same request, same 45 second timeout, in case the first one hit a passing hiccup.

  3. 3

    Full GET, 10 seconds after that

    A complete page request with a 45 second timeout. If this fails too, the site is reported down.

Alerts where you will see them

A downtime email read the next morning is not much use. Send the alert to wherever your team already works.

  • Email alerts arrive when a site goes down and again when it comes back up, with an optional daily reminder while it stays down and an alternative recipient for the alerts if you want one.
  • The mySites.guru Slack app posts the down and recovery alerts to Slack once you have connected it.
  • Webhooks post the alerts to a URL you paste, in Slack-compatible, Discord, Microsoft Teams, Google Chat or signed JSON format, so they can reach a chat channel or your own automation.
  • Desktop push sends the down and recovery alerts as notifications in your browser.
  • SSL expiry warnings arrive before a site's certificate expires, so it gets renewed before visitors see a browser error.

Alongside the alerts, each site has a 24-hour response-time graph and uptime percentages for the day, week, month and year, and client reports can include uptime sections.

Part of every plan, alongside everything else

Uptime monitoring is included in every paid plan, from the £5/month single-site plan to £19.99/month for unlimited sites. It is not part of the free audit, which looks at where one site stands today.

The same plan covers the rest of mySites.guru: vulnerability alerts, bulk updates and scheduled backups. See pricing for the details.

Common questions

How often are sites checked?
Every 5 minutes. A monitor is created for a site when you connect it, so there is nothing to set up per site.
How does it decide a site is down?
It sends a HEAD request. If that fails, it waits 10 seconds and tries another HEAD, then waits 10 seconds more and tries a full GET. Each attempt has a 45 second timeout, and only a 2xx status counts as up. A site is reported down only when all three fail. Why you might get a downtime alert for a site that looks fine.
My host or firewall blocks unknown traffic. What do I allow?
One address: 165.227.239.229. Every uptime check comes from it, so your host can allowlist it.
Where can alerts go?
Email on down and on recovery, with an optional daily reminder while a site stays down and an alternative recipient if the alerts should go to someone else. Alerts can also go to the mySites.guru Slack app, to desktop push notifications, and to a webhook in Slack-compatible, Discord, Microsoft Teams, Google Chat or signed JSON format. How the webhook formats work.
Is uptime monitoring part of the free audit?
No. Uptime monitoring is included in every paid plan: £5/month for one site or £19.99/month for unlimited sites. The free audit covers one site, needs no card, and shows where that site stands today.
