Meta Description
E海通海上卫星宽带综合信息服务的基础平台，主要由新一代宽带卫星、卫星船站、卫星地面站、E海通服务云等部分组成的天地一体、基于IP技术的宽带通信系统。 卫星资源 新一代卫星，可组合应用，灵活切换； 基于技术成熟Ku波段，容量大，抗雨雾能力强； 基于IP技术，系统部署简单、方便； 高带宽，船站可达下行4Mpbs，上行2Mpbs； 资费远低于传统卫星。支持个性化消费，可包月或按流量计费。 中海E云为了解决船-岸信息系统互联、互访而设计，实现公司船岸信息管理一体化的应用。船舶利用该系统以等效“专线”的方式访问公司陡岸内网各类应用系统，如OA系统、ERP系统、航运系统、财务系统、物流管理系统、船代业务系统等。同时，公司陆岸也可以随时访问船上各应用系统。 使用方便。支持手机、平板、PC等移动或固定终端接入应用，用户可随时随地、在任何网络环境下安全、快速访问公司内网各应用系统。 中海天鹰是专门针对卫星通信特征（带宽有限、资费昂贵、延时较大）而开发，实现陆岸对海上船舶的远程高清视频监控。中海天鹰在船舶安全生产、远程故障诊断、远程教育培训、应对突发事件等提升船舶管理效率方面有着极高的应用价值。 3D航姿仪是通过读取卫星船站的高精度惯导数据，经卫星传输，实现公司在陆岸查看在海上航行船舶的实时3D航姿，包括航向、航速、船位、水平姿态（横滚角、俯仰角）等，并提供本地显示。 海员E家借助船舶局域网，通过定时更新、自动更新等方式，为船员提供国内外和公司新闻资讯、党政工团报刊资料、船员培训课程及考试资料、电影电视、数字图书馆、有声读物等多功能、海量信息服务。

Don't just check uptime once — watch it 24/7

This is a one-time check. Turn on monitoring and we'll watch the domains that matter to you continuously, notifying you the moment anything moves across all three signals:

Uptime monitor with 7-day uptime percentage, failed checks, average latency by region, and daily outages

Uptime

We visit the site from multiple regions worldwide and email you within minutes if it goes down, with a per-region breakdown so a real outage stands out from a regional blip.

DNS changes

We watch NS, MX, CAA, CNAME, TXT and A/AAAA records, and identify the host, network, and ASN behind them, so a real migration or hijack stands out from routine noise.

TLS certificate

We warn you 30, 14, 7, and 1 days before it expires, and flag it if the issuing authority changes or the certificate is unexpectedly replaced.

Monitor uptime free

Free for your first domain: uptime, DNS, and certificate together. No credit card.

About Website Uptime Monitoring

This page shows whether we could reach a website the last time we checked it. We also keep a record of when it went down and came back, so you can see whether an outage is new or has happened before. For each site we show:

  • Website availability and response status
  • Server software and configuration
  • Meta information including titles and descriptions
  • Historical uptime patterns

What this page reports

  • Last status change: When we last saw a site switch between reachable and unreachable
  • Last downtime: When a site was most recently seen down, and whether it has come back
  • Server and meta information: The server software, page title and meta tags we last observed

We check a domain at most once a day and record an observation only when something changes, so these are the times a change was seen rather than the exact moment it happened. For continuous, minute-by-minute checks with alerting, use website monitoring.
