Progressive Web Apps

A Progressive Web App (PWA) is a web app that uses modern web capabilities to deliver an app-like experience to users. These apps meet certain requirements (see below), are deployed to servers, accessible through URLs, and indexed by search engines.

Progressive Web Apps are user experiences that have the reach of the web, and are:

  • Reliable – Load instantly and never show the downasaur, even in uncertain network conditions.
  • Fast – Respond quickly to user interactions with silky smooth animations and no janky scrolling.
  • Engaging – Feel like a natural app on the device, with an immersive user experience.

This new level of quality allows Progressive Web Apps to earn a place on the user’s home screen.

What is required?

To be considered a Progressive Web App, your app must be:

  • Progressive – Work for every user, regardless of browser choice, because they are built with progressive enhancement as a core tenet.
  • Responsive – Fit any form factor, desktop, mobile, tablet, or whatever is next.
  • Connectivity independent – Enhanced with service workers to work offline or on low quality networks.
  • App-like – Use the app-shell model to provide app-style navigation and interactions.
  • Fresh – Always up-to-date thanks to the service worker update process.
  • Safe – Served via HTTPS to prevent snooping and ensure content has not been tampered with.
  • Discoverable – Are identifiable as “applications” thanks to W3C manifests and service worker registration scope allowing search engines to find them.
  • Re-engageable – Make re-engagement easy through features like push notifications.
  • Installable – Allow users to “keep” apps they find most useful on their home screen without the hassle of an app store.
  • Linkable – Easily share via URL and not require complex installation.

Scheduled maintenance : Hostingmela Server

We hope you’re doing well today. As part of our commitment to provide the best possible infrastructure for your services, we have scheduled the following upgrade for the server on which your account for resides. Please read the following details carefully:

Reason for maintenance:
We’re always working to improve the performance and reliability of our services. As this server is currently running on legacy hardware, we’ve decided that an upgrade to our latest hardware and software configurations would be best to ensure that we’re providing the highest quality of service moving forward.

Our team is going to be taking your server offline in order to prevent any updates to websites during that time from being lost once the upgrade is complete. We will be backing up all server data, migrating it to the new server, and finally restoring the data. This full upgrade should improve performance and reliability for you and your clients across the board.

Maintenance Window:
START: Friday, March 23rd, 2018 @ 11:00PM IST
END: Saturday, March 24th, 2018 @ 11:00AM IST

Estimated Downtime:
We understand the importance of uptime for you and your clients and will be working as quickly as possible to complete this process. Your server will be taken offline during the process in order to prevent any changes from being made during the maintenance window. This will protect any data from being lost during the process. Still, we advise that you do not make any changes to your website after the full maintenance window has ended as we cannot guarantee such changes will transfer. In addition we highly encourage clients to backup any integral data prior to the migration and to thoroughly check and verify all sites and configurations post-migration.

Although we do not expect the downtime to last the entire maintenance window, we would advise you to prepare for 6-10 hours of downtime during the restore just in case. It is also important to read the notes below in order to prepare your account for this upgrade.

Upgrading from CentOS 6 to CentOS 7:

1) Latest version of cPanel

2) Password strength must be secure (cPanel will let you know if it is secure or not. We recommend several variables making sure to include caps, numbers, and symbols).

3) Upgraded version of MySQL which adds the Trigger option for MySQL privileges.

4) Older mail clients (such as Outlook 2010 and older, or older versions of Mozilla Thunderbird/MacMail) will no longer be supported on CentOS 7. We recommend that you upgrade your current mail client to one that can support TLS version 1.0 or higher, and uses ciphers other than Triple DES.

Thank you so much for taking the time to review this maintenance notice. If you have any questions or concerns about this upgrade, please don’t hesitate to contact our staff for more details.
