StatusCheck

Network Monitoring

The layers underneath the URL.

Most outages don’t start at the front door. StatusCheck checks the port behind it, the host under it, and the DNS record pointing at both.

Early access opens in batches. No spam, one email when it's your turn.

Included on every plan. Nothing here is an add-on.

Network Monitoring, in detail.

TCP ports

Databases, brokers, mail servers, SSH. A timed connect from each region you select, so you learn a port stopped accepting connections before an application does.

ICMP reachability

Ping with a packet count you set and a maximum acceptable loss. Min, average and max round-trip are recorded per region, and partial loss shows up as degraded rather than down.

DNS records

A, AAAA, CNAME, MX, NS, TXT, SRV, and PTR, checked against the resolver you choose with an expected-answer assertion. Catches a bad propagation before customers do.

Same confirmation rules

Network checks confirm across regions exactly like HTTP checks. A single region failing to reach a host is far more likely to be that region’s problem than yours.

The specifics

Check types and what each one proves

Written out in full, because “monitoring” means something different at every vendor.

TCP
Port accepts connections: host, port, timeout
ICMP
Host reachable, loss within bounds: packets per check, max loss, timeout
DNS
Records resolve as expected: record type, resolver, expected answer
