Assuming both trains leave at the same time:

1. Train from Chicago speed: **60 mph**
2. Train from New York speed: **80 mph**
3. Since they are moving toward each other, add their speeds:

\[
60 + 80 = 140 \text{ mph}
\]

4. They are **900 miles** apart, so time is:

\[
\text{time} = \frac{900}{140}
\]

\[
\text{time} = 6.428571\ldots \text{ hours}
\]

5. Convert the decimal part:

\[
0.428571 \times 60 \approx 25.7 \text{ minutes}
\]

So they meet after about:

\[
\boxed{6 \text{ hours } 26 \text{ minutes}}
\]

More exactly, they meet after **6 hours, 25 minutes, and 43 seconds**.

Assuming **“this week” = Jun 16–22, 2026**:

- **Cloudflare service incident:** Cloudflare reported increased error rates/latency from 13:35 UTC today, affecting Analytics, CDN/Cache and Durable Objects; it later pointed to a fiber cut in Eastern North America and said traffic engineering had mitigated most congestion/packet loss. ([cloudflarestatus.com](https://www.cloudflarestatus.com/incidents/v3yl7jqmqj51))
- **New anti-bot/privacy protocol:** Cloudflare announced work with Mozilla Firefox, Google Chrome, Microsoft Edge and Shopify on **Private Access Control Tokens (PACT)**, meant to verify legitimate humans/agents without CAPTCHAs or invasive tracking. ([cloudflare.com](https://www.cloudflare.com/press/press-releases/2026/cloudflare-collaborates-with-leading-browsers-to-develop-a-privacy-first-protocol-for-the-global-internet/))
- **AI + SASE partner push:** Cloudflare launched a **Cloudflare One Design Partner** program and **Cloudflare One Stack**, giving select partners AI-powered workflows to help customers deploy and manage Zero Trust/SASE migrations. ([cloudflare.com](https://www.cloudflare.com/press/press-releases/2026/cloudflare-launches-design-partner-designation-to-accelerate-secure-ai-and-seamless-sase-adoption/))
