* Customer-based specification of the interval at which LinkAlert monitors a specific domain, IP, gateway or server, as well as notification intervals during a detected failure and/or a change or modification to a given URL/Web-accessible document.
* Multiple Messaging Devices are supported, including Voice (test to speech) notification to regular (POTS) telephone lines. Interpag'es LinkAlert can message to:* Specific ports may be tested, such as 25 (SMTP), 80 (HTTP), as well as non-published ports and those running custom services.

* Web Data Changes: Customer-based specification of a given Web page(s) or URL(s) to monitor for complete failure or modification/changes from previous checks.
* Instant User Configuration of nearly all aspects of their LinkAlert monitoring service. Users may create, delete, or modify the monitoring of a given Web Site, SMTP Server, Ping or other IP Port, Secure Server, or any server or machine connected to the Internet at will, with changes taking effect instantly. Try the Linkalert WWW Configuration Menu for a free demonstration; (guest access permitted, do not use a password).
* Link/Service Restored notification (optional, configurable by the user) indicates when a problem has been corrected or has corrected itself.
* Thresholds for link or server failure notifications, eg, how many consecutive failures are required before an alert is dispatched. (This helps eliminate "false positive" alerts due to system reboots, network latency, etc.)
* Alternate notification to other pagers, e-mail addresses, fax machines, and text-to-speech voice alerts, in the event that a failure is not corrected in a user-defined period of time. LinkAlert customers may specify fallback notification accounts, so that in the event that the first person (or group) which is notified fails to respond, a second, third, etc. person (or groups) will be subsequently notified.
* E-Mail Notification Suspension to allow maintenance and scheduled downtime to be free of continued alerts from LinkAlert. Simply send a specially worded and authenticated e-mail message to LinkAlert, and notification will cease for the period of time specified in your e-mail.
* Modification Monitoring Configuration: Set your LinkAlert account to only monitor given sections of a Web page for changes so banner ads, minor changes, and other variable content don't generate false alerts.
* Multiple Data Centers in geographically disparate areas with differing Internet connectivity providers (including wireless and satellite) continuously monitor target sites from a variety of "positions" on the Internet and provide for redundancy in the event of anetwork outage at a given data center. Please review the Reliability/SLA page for details.
* Intertalk access from any touch tone telephone, which allows LinkAlert customers to dial into our server and suspend pager notification while your support staff is aware of a failure and working to correct it. Intertalk also allows for e-mail header verbal transcription to check previous alerts in the event a page was missed, and the ability to remotely fax alerts to any fax machine if you are not near a terminal and need to find out the status of a given site/link failure.
