@DrizzleORM What page is it taking you to?

@tkadlec It does not, but even if I go and manually filter - it never shows anywhere near that amount of errors

where can I inspect those in CF? (clicking arrow leads to a completely unrelated page)

@DrizzleORM That being said, we're working on giving users a LOT more visibility and power here. What would your dream scenario be here to see next?

@DrizzleORM It _should_ be taking you directly to your analytics filtered to those response codes (ex: clicking 4xx takes you to a page filtered to only the requests that triggered 4xx, clicking 5xx takes you to a page filtered only to requests that triggered 5xx)

@Dan_The_Goodman well that seems excessive wanna DM me some details and I can dig in?

cloudflare, what

Amazing how many @Cloudflare products start with a vendor we’d happily used deciding to try and hold us hostage. And our team then saying: “Ok, guess we need to build that ourselves now.” DDoS, DNS, Registrar, CAPTCHA, Zero Trust… all the result of this. Any guesses what’s next?

Is TTFB a hot new metric? No. Is it a key #webperf metric for tracking responsiveness? YES! Slow TTFB virtually guarantees your site will deliver a poor #UX. Bonus: It's widely available across browsers! @tkadlec explains how to diagnose TTFB issues... speedcurve.com/web-performanc…

Exciting new product updates from our awesome dev team! Long story short: We've made it easier and faster for you to find and fix the issues that are hurting your Vitals metrics! #webperf #corewebvitals #ux

@philhawksworth 😂 nope

@AWSSupport Got a ticket open

@tkadlec Sorry to hear, Tim! I found this article that may be helpful: go.aws/3Tb4pSj. If not, I recommend reaching out to our Support team, so they can do a deeper dive: go.aws/support-center. ^LG

Err...this is gonna sound crazy, but I'm pretty sure AWS is...randomly deleting dynamoDB items? My app has one & only one point where it deletes items and I can see no record in CloudTrail of anything being deleted, yet every day a couple random items just...aren't there anymore

@oferbel No...that's what I thought too, but nothing there.

me anytime I try to figure out how to accomplish anything in the AWS UI

ok hold up how long has this been there without me noticing chrome drawing a red line between style recalc and the method that triggered it in their flame charts

Keeping your site fast is a crucial endless game. Yet it's perilously easy to lose focus. @tkadlec uses the analogy of guardrails (automated testing & alerts) and breadcrumbs (deployment tracking) to make #webperf more visible throughout the dev process. speedcurve.com/blog/continuou…
