NGINX Safe Reload Add-on for PaaS
The NGINX Safe Reload add-on adds a one-click action to NGINX layers on MassiveGRID PaaS that validates the configuration syntax and, only if it passes, reloads NGINX gracefully without dropping connections. It removes the two classic risks of editing NGINX: a broken config taking the site down, and a restart interrupting users.
Both buttons open the MassiveGRID PaaS dashboard with NGINX Safe Reload pre-selected. The trial needs no credit card.

What is NGINX Safe Reload?
Editing NGINX configuration is routine: a new server block, a redirect, a header, a cache rule. Applying it is where things go wrong. A restart briefly drops connections, and a typo makes NGINX refuse to start, leaving the site offline until someone fixes the file. The correct procedure is to run a syntax test first and then send a reload signal, which starts new worker processes and lets old ones finish their requests.
The add-on packages that procedure as a button in the dashboard and runs it on every node of the layer in sequence. If the test fails on any node, nothing is reloaded and the error is shown. It is used by other add-ons, including Let's Encrypt, to apply certificate changes safely.
What NGINX Safe Reload Changes in Your Environment
Add-ons run against an environment you already have. Nothing is rebuilt, and the change can be removed from the same dashboard.
- Configuration test: Runs the NGINX syntax check against the current configuration on each node.
- Graceful reload: Sends the reload signal so new workers start with the new config while old workers finish in-flight requests.
- Rollback safety: If the test fails, the running configuration stays untouched and the error is reported.
- Layer-wide action: Runs across every NGINX node in the layer, one at a time.

Why Run NGINX Safe Reload on MassiveGRID PaaS
Built for uptime. NGINX Safe Reload runs on MassiveGRID's high-availability platform, where every environment is covered by a 100% uptime SLA. Nodes live on redundant hosts, storage is replicated, and failed containers are restarted or migrated automatically.
Pay for what you use. Billing is hourly and per cloudlet (128 MiB RAM plus 400 MHz CPU). Vertical auto-scaling adds and removes cloudlets as load changes, so a quiet NGINX Safe Reload environment costs a few dollars a month and a busy one grows without a migration. Full details are on the PaaS page.
Your choice of jurisdiction. Deploy in New York, London, Frankfurt or Singapore and keep data inside the region your users or regulators require. MassiveGRID is ISO 9001 certified and GDPR compliant, and has run hosting infrastructure since 2003.
No lock-in. The package is a standard Jelastic Packaging Standard (JPS) manifest. You keep root-level access to the containers, can export the manifest, and can move the workload to any other Jelastic-compatible platform or to your own servers at any time.
