Performing operations on nodes of distributed computer networks

A non-transitory computer-readable medium storing instructions executable by data processing apparatus to perform operations comprising:

• identifying a request to upgrade a first computer node in a computer network, the first computer node being a first acceleration node to accelerate transmission of resources between a client computer system and a server computer system connected through the first computer node;
• identifying a second computer node in the computer network linked to the first computer node, the second computer node being a second acceleration node to accelerate transmission of resources between the client computer system and the server computer system connected through the second computer node;
• establishing a bypass link to the second computer node from the first computer node, the bypass link configured to transmit new connections received for handling by the first computer node to the second computer node for handling by the second computer node during upgrading of the first computer node;
• and
• upgrading the first computer node upon establishing the bypass link in response to identifying the request.
