If the network infrastructure connecting the server to the web is stable and used, it can restrict the data transmission rate and cause delays in answering queries. This congestion can make it impossible for the server to respond to requests in a reasonable period as the situation becomes overboard.

Try to use a Proxy:
Several blocks are online sources that try to restrict access to them, and others are proxy servers. A proxy server may allow you to troubleshoot a website due to the large amount of traffic on the network or sites that are being loaded from the network.
