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…

NEW! Based on your feedback, we've expanded your capabilities for on-demand testing! This how-to post covers: 🟡 Scheduled vs on-demand tests 🟡 Run on-demand tests for site or custom URL 🟡 View & compare test details 🟡 Group tests as a deploy speedcurve.com/blog/on-demand… #webperf

Site speed isn’t something you fix once and walk away from. @tkadlec offers pro tips on how to set up continuous monitoring – as part of your CI/CD process – so you can fight regressions and stay fast. speedcurve.com/blog/continuou… #webperf #sitespeed #pagespeed #cicd

👀 Well hello there! @SpeedCurve

Kind of snuck under the radar, but love that @speedcurve has navigation types as a filter now. Extremely useful!!
