Npm Outage Feb 17th
Caused by a Cloudflare DDoS protection bug
- Cloudflare tweaked HTTP header rules to identify bad traffic
- Npm uses a non-standard "install" referer
- Cloudflare started treating npm installs as DDoS attacks on npm!
- They reverted, but npm was basically down for 2 hours
Great reminder to prepare for such things
An Interesting Bug
- In 2018, Docker and Razer Synapse could not run together
- Each program intended to limit to one running copy of itself
- They both did something like this:
string.Format("Global\{0}", (object) Assembly.↵
GetExecutingAssembly().GetType().GUID);
Can you spot the bug?An Interesting Bug
string.Format("Global\{0}", (object) Assembly.↵
GetExecutingAssembly().GetType().GUID);
.GetType() returns .NET's System.Reflection.RuntimeAssembly
- So each app was sharing .NET's GUID
- Apparently this was from a flawed StackOverflow answer
- Beware the uncritical copy/paste!
