Yes. The free plan checks every minute and allows up to 55 monitors and 20 alerts, and an alert can go to Telegram. Several chats are fine as long as you stay within the 20 alerts.

How fast does the alert arrive?

With a 1-minute interval and the default of 3 failed checks in a row, within a few minutes of the site going down. You can lower the number of failed checks to 1 for a faster but more nervous alert.

Can alerts go to a group or a channel?

Yes. Press “Add the bot to a group” in the form, or add the bot to a channel as an admin with the right to post. Forum topics are not supported yet.

Websites and APIs over HTTP(S), ports, ping, DNS, SSL certificates, mail servers, proxies, IP cameras and heartbeats from cron jobs: every monitor type can alert to Telegram.

What language are the messages in?

Russian or English, in the language of the monitor owner's account.

What if Telegram is unreachable?

A send gets up to 3 attempts, and when Telegram asks to slow down for up to 30 seconds, the bot waits. For an important site add a second channel as well: email, web push, Slack or a webhook.

Website down alerts in Telegram

PingZen checks your site and messages Telegram when it stops answering and when it is back: with the error, the status code and how long it was down. To your own chat, a team group or a channel.

PingZen

bot

The real message layout with an example site. Which lines a message carries is set per alert; the checker location and the account can be added.

The PingZen alerts page: three alerts going to Telegram — a personal chat, an on-call group and a status channel — and one to email — Alerts to a personal chat, a team group and a channel next to an email one. Demo data.

Connect in three steps

No bot tokens and no chat ids to copy: the link carries a one-time code and PingZen picks up the chat itself.

Press “Connect Telegram”
In the alert form, choose Telegram and press the button. Telegram opens with the @pingzen_bot chat.
Press START
The bot gets a one-time code from the link and ties the chat to your account.
Come back — done
The form sees the chat by itself. Send a test alert to check that it arrives.

For a team: “Add the bot to a group”, or add it to a channel as an admin allowed to post. Signed in with Telegram? Your personal chat is already connected. The chat id can also be typed in by hand.

The PingZen alert form with Telegram chosen: personal chat, group or channel, the three connection steps, a Connect Telegram button and Send test — The alert form: pick Telegram and the recipient.

What arrives in Telegram

The site is down

After 3 failed checks in a row by default (1 to 10, your choice), so one network hiccup does not wake you up.

The site is back

After 2 good checks, with how long the outage lasted.

Still down — reminders

If you turn them on: after 5 minutes, 15 minutes, an hour, then every 4 hours until it is fixed.

Certificate expiring

A warning before the SSL certificate runs out, at most once a day.

A heartbeat did not arrive

A cron job, a backup or a script stopped reporting in on time.

Degraded and slow, if you want them

HTTP 429, bot-protection blocks, a domain about to expire, answers slower than 5 seconds — separate from “down”, and off by default.

Alerts you will not mute

Flapping is held back

A site that keeps bouncing between up and down does not send a message on every bounce.

Cooldown

5 minutes between messages of one alert by default, adjustable from 0 to 24 hours.

Maintenance windows

During planned work alerts stay quiet.

When the bot loses the chat

If the bot is removed from a group or blocked, the alert is switched off and we email you about it if your account has an email, so nothing fails silently. A group turned into a supergroup is followed automatically.

What the Telegram bot does not do

No buttons. Besides /start and /help it knows only /link, which connects a channel once; the rest of the time it only sends alerts.
No phone calls, SMS or on-call escalation.
No quiet hours and no choice of a forum topic.
