See every DNS change, with the before and after.
Pingerer keeps a copy of your A, AAAA, CNAME, MX, NS and TXT records and tells you when any of them change.
DNS records decide where your website, email and other services live. When one changes, by mistake, during a move or because an account was taken over, things break in confusing ways. Pingerer tells you as soon as it happens.
What we watch
Your domain's A, AAAA, CNAME, MX, NS and TXT records, looked up every 15 minutes. You choose which ones matter.
Before and after
Every DNS alert shows exactly what was removed and what was added. If you made the change, mark it as expected and that becomes the new normal. If you didn't, you know right away, with the old values in hand to put back.
Common things it catches
- A new web host or developer changed your
Arecord and the old site disappeared. - Your
MXrecords changed and email stopped arriving. - Your nameservers (
NS) moved, which can mean a registrar transfer, or someone else in control of your domain. - A
TXTrecord for SPF or a verification was deleted.

Uptime monitoring
HTTP, keyword, ping and port checks as often as every 30 seconds, confirmed from more than one region before anyone is woken up.
SSL & domain expiry
Reminders before your SSL certificate or domain registration runs out, plus broken certificate chains and wrong hostnames.
Email deliverability
Plain-English checks of SPF, DKIM and DMARC, so the emails your business sends keep arriving.
Heartbeats
Your cron jobs, backups and workers ping a URL when they finish. If one goes quiet, you get an alert.
