AlertSite has no write-up on Specifiction yet; its figures are above.

WebSitePulse is a web-based service for monitoring servers, network equipment, websites, web applications, and email infrastructure 24/7/365. Checks can run as often as every minute or as infrequently as once a week, with geographically distinct monitoring locations available for each target. Its listed services cover uptime, webpages, web transactions, email round trips, vulnerabilities, blacklists, and certificates. Before sending an alert, the service detects an error, independently confirms it, and checks it against the notification level. Alerts can go by email, SMS, voice call, instant messenger, pager, SNMP trap, or URL. Reports include uptime and downtime summaries, response-time breakdowns, and downloadable raw data; WSDL and HTTP APIs provide real-time target data. Vulnerability monitoring checks servers and firewalls for more than 60,000 known security issues and exploits and offers recommendations. Dedicated Android and iOS apps support push notifications. Plans are listed from $3/mo, and a free plan and trial are available subject to account and eligibility terms.
