 If the fee paid on the source blockchain is within an acceptable range of the execution cost on the destination chain, the message will be transmitted as soon as possible after it is blessed by the Risk Management Network. If the cost of execution increases between request and execution time, CCIP incrementally increases the gas price to attempt to reach eventual execution, but this might introduce additional latency.
 
 Execution delays in excess of one hour should be rare as a result of _Smart Execution_. The Smart Execution time window parameter represents the waiting time before manual execution is enabled. If the DON fails to execute within the duration of Smart Execution time window due to extreme network conditions, you can manually execute the message through the [CCIP Explorer](https://ccip.chain.link/). Read the [manual execution](/ccip/concepts/manual-execution) conceptual guide to learn more.

-## CCIP Upgradeability
-
-All onchain configuration changes and upgrades to CCIP are processed through a [ManyChainMultiSig.sol](https://github.com/smartcontractkit/ccip-owner-contracts/blob/main/src/ManyChainMultiSig.sol) (MCMS) contract, which requires a quorum of independent parties to approve.
-
-Any proposal must either (1) be proposed by a dedicated MCMS contract and then be subjected to a review period, during which the node operators securing CCIP are able to veto the proposal; or (2) be proposed by a dedicated MCMS contract and be explicitly approved by a quorum of independent signers, including multiple node operators securing CCIP, providing an alternative path during time-sensitive circumstances.
-
-Any onchain update that passes the review period without a veto becomes executable by anyone, which can be done by running a [timelock-worker](https://github.com/smartcontractkit/timelock-worker) to process executable upgrades.
