FAQ
Frequently Asked Questions
Yes, all six tools are completely free to use with no login required. You can run SSL checks, DNS lookups, uptime tests, latency measurements, traceroutes, and port scans from multiple regions without creating an account. Registered users get access to additional features like scheduled monitoring and historical results.
ProbeOps runs probe nodes in 6 regions across 4 continents: US East (Virginia), US West (Oregon), Canada Central, EU Central (Frankfurt), AP South (Mumbai), and AP Southeast (Sydney). Each diagnostic runs simultaneously from every region so you can compare results worldwide.
Traditional tools test from one server, so they miss regional DNS propagation delays, CDN misconfigurations, and geo-routing errors. ProbeOps tests from 6 locations at once, giving you a global view of how your infrastructure actually performs for users in different parts of the world.
No installation is needed. All tools run entirely in your browser using our distributed probe infrastructure. Simply enter a domain name or IP address, click run, and get results within seconds from all probe regions.
Free users can run on-demand tests at any time. Registered users on paid plans can schedule recurring probes, set up alerts for SSL expiration or downtime, and access a full history of past results through the dashboard.
The DNS tool supports A, AAAA, CNAME, MX, TXT, NS, SOA, and PTR record types. The port checker supports TCP and UDP scans on any port. Traceroute supports both ICMP and UDP protocols. The SSL checker validates full certificate chains including intermediate certificates.
