Claude.ai went down on April 28, 2026, leaving users unable to access the service. Anthropic acknowledged the incident on its status page, confirming that Claude was unavailable. No root cause was published at time of writing.
Outages like this are a reminder of the real cost of depending on a single AI platform for daily work. If your business runs on Claude for client deliverables, drafting, or customer support, a down period - even a short one - means stopped work. Anthropic has generally maintained solid uptime, but this is the second notable disruption in recent months.
If you run anything time-sensitive on Claude, it's worth having a backup option set up. Claude for Desktop was similarly affected. Users who need continuity during outages should consider keeping a secondary tool configured and ready - not because outages are frequent, but because when they happen, they always happen at the wrong time.
