+### How to check if AMB is down (not relaying message)
+
+In certain circumstances, i.e. hardfork, AMB will be planned for downtime (not relaying message) to ensure security of the bridge. Planned downtime will be announced in public channel like Discord and Twitter, prior to the event.  
+There is also another way to check whether the AMB is down or not by reading `maxGasPerTx` value on AMB contract.
+
+In the current configuration, `maxGasPerTx` is set to 4000000 on [Ethereum](https://etherscan.io/address/0x4C36d2919e407f0Cc2Ee3c993ccF8ac26d9CE64e#readProxyContract) and 2000000 on [Gnosis Chain](https://gnosisscan.io/address/0x75Df5AF045d91108662D8080fD1FEFAd6aA0bb59#readProxyContract).
+
+The AMB is down when `maxGasPerTx` is set to 0, only by owner of the contract.
+
+By setting `maxGasPerTx` to 0, the [condition in `_sendMessage()`](https://github.com/gnosischain/tokenbridge-contracts/blob/master/contracts/upgradeable_contracts/arbitrary_message/MessageDelivery.sol#L40) will not pass, meaning, the bridge is down/stopped.

-* Also affects other networks
-* Not seen in 2.36.1 yet
-* Work going on for withdrawals (for Ethereum mainnet)

-* Will launch a website with the new public RPC
-* Launching checkpoint sync for Chiado (probably today)

-* Looking into looking a bridge validator on Chiado, and then on mainnet
-* Waiting for Giacomo to accept traffic on the RPC

 ### Stefan: Increase base fee to 1GWEI? ‍
-* Allows us to make constant spamming very costly. Currently it is too cheap.
-* Current base fee: 7 wei -> extremely cheap to spam the network for a long time
-* Increasing the base fee to 1 gwei would make it expensive to spam the network even for 10 minutes
-* Would require a simple hard fork, which could be included in another hard fork
-‍
-#### Jorge (Nethermind)‍
-* No strong opinion
-* The computation limit is bound by the gas limit anyways
-* Sustained loads would increase the gas price exponentially as per EIP-1559
-* On Chiado, a spam of 30 - 60 minutes increased the base fee to hundreds of gwei
-* The main idea is to prevent nefarious actors to put relevant transactions on hold for some time, which would degrade user experience
