Must be the first time today that I have experienced serious downtime for Claude Code. Apparently Anthropic is having a very hard time keeping up with customer demand. Wait until it IPOs? .... Price will skyrocket.

I ask Claude: "How come Claude Code is having problems?"
For the immediate fix: there isn't a client-side one. When it's an infrastructure outage, the official status page is the thing to watch — status.claude.com — rather than reinstalling, re-authing, or fiddling with your config, which won't help and can just add noise.
Worth a bit of caution on the "why," though. A lot of the coverage above is from third-party blogs and aggregators speculating about root cause — sub-agent loops, capacity bottlenecks, and so on — and Anthropic itself had not released an official post-mortem at the time those pieces were written. I'd treat the specific technical explanations as unverified until Anthropic posts its own incident report. The one solid fact is that there's a real, acknowledged multi-platform disruption today. Collabnix
This is also part of a pattern worth noting if Claude Code is load-bearing in your workflow. There have been recurring stability incidents across 2026 — notably March 2, June 2, and June 18 — coinciding with sharp growth in usage. One of the earlier ones had a costly wrinkle for paid users: the June 2 disruption was traced to a bug in Claude Code's sub-agent system, where sub-agents multiplied in an infinite loop and spiked token consumption. If you were running Claude Code around that date, it's worth glancing at your usage to confirm nothing ran away. AimadetoolsAimadetools
The broader takeaway that the engineering-press coverage keeps landing on is one you'll recognize from 40 years of building systems: hard-coding a single provider's endpoint is a single point of failure, and the resilience options are multi-LLM redundancy with automated failover — at the cost of added complexity and the need for a solid eval suite to confirm each model produces acceptable results. For ValEngr specifically, that argues for keeping your API-calling layer model-agnostic enough that you can fall back from Opus to another model without rewiring, which dovetails with the fallback-handling work we were already discussing for Fable. "
Here are the most recent figures, though "how many customers" splits into a few different numbers depending on what you're counting.
Business customers: Anthropic serves over 300,000 business customers as of its Series F announcement. That figure has held steady across reporting into mid-2026 — it's the number Anthropic itself cites. For scale, that's up from fewer than 1,000 business customers two years prior. Claude API Docsmexc
High-value enterprise accounts, which is where the growth is most dramatic: the number of customers spending over $100,000 annually has grown roughly 7x in the past year. At the top end, the $1M+ tier moved fast — over 1,000 customers now spend more than $1 million annually, having doubled from 500+ in under two months as of April 2026, up from about a dozen two years ago.
Individual users (the consumer side, harder to pin down since Anthropic doesn't publish a single official number): third-party estimates put it around 18.9 million monthly active users on the web, plus additional millions on mobile. The app specifically was estimated at 12.48 million monthly active users in February 2026, up about 49% month over month.
A couple of caveats worth keeping in mind, since you work with this kind of data:
The 300,000 "business customers" figure is the one Anthropic states directly, so it's the most reliable. The MAU numbers are third-party analytics estimates (Similarweb, AICPB, and similar), not official disclosures, so treat them as directional. And one all-in figure you'll see floating around — a claim of close to 300 million total users including indirect API users — is a loose estimate that mixes direct and indirect usage, so I'd be skeptical of it as a precise count. TechRadar
Also worth noting given the API work you're doing: enterprise and startup API calls drive the majority of revenue through pay-per-token pricing, with business customers accounting for roughly 80% of revenue. So as a solo S-Corp API user, you're part of that 300,000+ business-customer count rather than the consumer MAU figures — the long tail of API developers is folded into that business number."

I ask Claude: "How come Claude Code is having problems?"
Claude responded: "Let me check whether there's an active incident or known issue with Claude Code right now.
... There's an active outage today. Claude is experiencing a widespread service outage on June 18, 2026, with disruptions starting around midday and complaints spiking sharply, affecting Claude Chat, the website interface, and Claude Code. Users are seeing complete server timeouts, no chat responses, and login errors. So if Claude Code is erroring out or hanging for you right now, you're not alone and it's almost certainly the platform-wide incident rather than anything on your end.
