Is Bing immune to DDOS attacks?

Hello MS Community,

as part of a university / cyber security course we were discussing hypothetical DDOS cases, and I discussed in theory whether a MS service could be brought down with a DDOS attack. As an illustrative case I brought up the case that Bing might be flooded with requests and, at least, partially, go down in one area or a full continent etc.

Can we share any insights, how large (Tbps) the attack had to be and how much downtime we would find acceptable, and in how short a timeframe services could be restored?

Any help is highly appreciated (if such insights were open to sharing publicly),
Thanks in advance!

I would assume there must be connection policy settings like - (a) how many connections are allowed from same source/IP in a given interval, let's say in a minute, before those connections are blocked or dropped (b) how many concurrent connections are allowed from same source in a given interval before throttling further connections (c) a generic URL blacklisting check from known 3rd party databases before accepting connection from a source (d) reputation checks for the source. All these checks must be going in the background to reduce the DDoS but yes I am also interested to know further details, and questions that tosebek has asked above. Would be nice if someone from MS Bing community can share more details, I will continue to monitor this thread! Thanks

I understand that you are looking for DDoS Protection limits for Bing's services. However, since this is not an Azure question, I cannot provide you information regarding the same. Bing team does not monitor these threads. I can definitely let you know some details regarding how Azure handles DDOS which is discussed here -what-level-of-ddos-can-azure-handle.html. If you have any further questions regarding how Azure DDOS works, please let us know further and we will be glad to assist. Thank you!
