This Acceptable Use Policy ("AUP") applies to everyone who uses SiteDownCheck at https://sitedowncheck.com, including the free tools, monitors and the API. It forms part of our सेवा की शर्तें. We keep the rules short and practical.
1. Purpose
SiteDownCheck exists to help people find out whether websites are reachable and healthy. Our checks are light-touch HTTP, DNS and TLS requests. We do not want the service used to harm other people's systems, to reach private networks, or to overload our own infrastructure.
2. What you must not do
2.1 Test sites without permission
You must not use the service to stress, flood, probe or repeatedly hit a website that you do not own or do not have permission to test. Occasional checks of a public site, such as seeing whether it is up, are normal. Repeated, high-frequency or intrusive use against someone else's site is not.
2.2 Scan internal networks
You must not try to use the service to reach internal or private networks, local addresses, cloud metadata addresses or non-web ports. This includes attempts to disguise such targets through redirects, unusual hostnames, DNS tricks or alternative IP formats.
2.3 Circumvent limits
You must not bypass or interfere with rate limits, monitor caps, API quotas or other technical measures. This includes rotating IP addresses or creating many keys or monitors to get around limits.
2.4 Bulk scraping and excessive automation
You must not run automated bulk collection or scraping of the service beyond the published API limits (the free API allows 200 calls per day per key). If you need more capacity, contact contact@sitedowncheck.com first.
2.5 Harass or harm
You must not use monitors, webhooks, alerts or status pages to harass, spam or intimidate anyone, for example by pointing webhook alerts at a third party's endpoint, or by publishing misleading or defamatory content on a status page.
2.6 Break the law
You must not use the service for any unlawful purpose, to infringe someone's rights, to spread malware, or to support fraud, phishing or other abuse.
2.7 Attack the service
You must not attempt to disrupt, overload, reverse engineer for attack purposes, or gain unauthorised access to the service, its data or its users. Security researchers should follow our Security Policy.
3. Safeguards built into the service
Several limits are applied by design, not as a judgement of any individual:
- Private, loopback, link-local and other internal addresses are blocked.
- Only standard web ports are allowed for website checks.
- Requests are rate limited per IP address.
- Monitors are capped (3 on the free plan, 5-minute minimum interval) and capped per network.
If a check is refused for one of these reasons, it is working as intended. Please do not attempt to get around it.
4. Your responsibilities
- Make sure you have permission before monitoring or testing a site you do not own.
- Keep your monitor links and API keys private.
- Make sure webhook URLs belong to you or to someone who has agreed to receive alerts.
- Do not put confidential information in monitor names that may appear on public status pages.
5. Reporting abuse
If you think someone is misusing the service, or that requests from our servers are being used against your website, email contact@sitedowncheck.com. Include the website or address affected, the approximate time (with time zone), and any log lines that show our requests. We will review it and respond as soon as we reasonably can.
6. Enforcement
If we believe this AUP has been broken, we may, at our discretion and with or without notice:
- rate limit or throttle the activity;
- block an IP address, range, domain or key;
- disable or delete monitors, keys or entries;
- suspend or end access to the service;
- report unlawful activity to the relevant authorities and cooperate with lawful requests.
We try to be proportionate. A first, minor or accidental problem may lead to a warning or a simple limit, while deliberate or serious abuse can lead to an immediate block.
7. Changes
We may update this AUP as the service changes. The date at the top shows the latest version. Continued use after a change means you accept the update.
8. Contact
Questions about this policy or reports of abuse can be sent to contact@sitedowncheck.com.
