Hi More often I get this error: ---------------------------------------- 503 Service Unavailable No server is available to handle this request. ----------------------------------------- But when I refresh, site uploads again. Please help how to rectify this error. Thanks
This error means your website is temporarily overloaded. On some hosting providers it means you've met their maximum number of concurrent connections. For shared hosting this could be 50 concurrent sessions, for others it is 100 concurrent. I use load balancing across multiple servers to avoid this, it only takes a small burst of traffic to block a single buyer. You can also block errand spiders and referrer spam, that will bring down your concurrent connections. Best, Justin
