What happened was we had SYN attacks to some workloads. You may have had Cloudflare in front of your app, however, non WAF workloads could have affected the availability. As such we have implemented short terms measures to prevent this moving forward. Since then we've expanded interconnect capacity with new peering and Direct Connect, deployed per-container eBPF firewalls, hardened our edge, and built continuous connectivity monitoring between hosts. We're also rolling out a WAF for all customers, edge-level protection against malicious request patterns across all plans.

Was this one recent?

Yes recent, almost happens daily since last week.

Then you should be good going forward, but please do let us know if you continue to see this, and we can dig in further!

Okay, let's check in again in a couple of days. Really like the platform, sad to see if the service quality is not optimal.

By the way this is the response time on last 7D, last occurence is ~5 hours ago. You can see sometimes it went up to 30s. I had to restart it to make it work again.

Noted, please keep an eye on it and let us know if it spikes again.

ummm...

anyway, how to make sure its on my app side or on railway side?

edit:
cpu/ram usage seems normal on my end

Some form of APM and tracing is underrated and underutilized. Adding that to your app would help with so much.

okay i finished set up a monitoring and tracing. for now will resolve the thread. will report again if still happens.

thank you
