Complex applications means complex rules.
In the last three episodes of this series, we discussed getting a copy of SnapRoute’s BGP code using Git, we looked at the basic structure of the project, and then we did some general housekeeping. At this point, I’m going to assume you have the tools you need installed, and you’re ready to follow along as we ask the code questions about how BGP actually works.
Now, let’s start with a simple question: how does BGP bring a new peer up?
It seems like we should be able to look for some file that’s named something with peering in it, but, looking at the files in the project, there doesn’t seem to be any such thing (click to show a larger version of the image below if you can’t read it).
Hmmm… Given it’s not obvious where to start, what do we do? There are a number of options, of course, but three options stand out as the easiest.
ARM gets a buyer; SoftBank gets ... more debt?

We have rolled out automatic protection for all customers for the the newly announced vulnerability called httpoxy.
This vulnerability affects applications that use “classic” CGI execution models, and could lead to API token disclosure of the services that your application may talk to.
By default httpoxy requests are modified to be harmless and then request is allowed through, however customers who want to outright block those requests can also use the Web Application Firewall rule 100050 in CloudFlare Specials to block requests that could lead to the httpoxy vulnerability.
