2026 Network Outage Report: What Hosting Buyers Need to Know About Internet Health
Cisco ThousandEyes has published its weekly internet health check throughout 2026, tracking global network outage events across ISPs, public cloud, collaboration apps, and edge networks including DNS and CDNs. The latest week of August 17–23 recorded 534 global outages, a slight 2% drop from the prior week, but U.S. cloud network outages rose 22%. For hosting buyers, website owners, and sysadmins, these figures are not abstract: they translate into latency spikes, broken migrations, and downtime. This article breaks down the 2026 outage trends, highlights notable provider failures, and explains practical resilience steps using data from ThousandEyes and Uptime Institute’s 2026 resiliency survey.
ThousandEyes 2026 Outage Trends: Global vs. U.S. and Cloud Spikes
The ThousandEyes data set compiled by Network World runs from late December 2025 through late August 2026. The weekly global outage count started at 199 for Dec 29–Jan 4, climbed to a peak of 610 for July 20–26, and settled at 534 for Aug 17–23. U.S. outage totals tracked similarly, hitting 457 in the July 20–26 week before easing to 366 in the latest report.
The category breakdown matters more than the headline number. ISP outages globally fell 15% week-over-week to 252 in the Aug 17–23 window, and U.S. ISP outages dropped 12% to 148. However, public cloud network outages moved the opposite direction: global cloud outages rose 17% to 189, while U.S. cloud outages jumped 22% to 174. That is not a one-week blip. In the July 6–12 week, global public cloud outages surged 72% to 234, and U.S. cloud outages leapt 84% to 221. Collaboration app outages remained rare—usually zero to two per week—so the instability is concentrated in transit and cloud backbone layers.
For hosting operators, the signal is clear: residential ISP friction is improving slightly, but the infrastructure that carries VPS, cloud server, and managed hosting traffic is experiencing more frequent network-layer disruptions. The research does not name individual hosting control panels or WordPress deployments in the counts, but any workload riding on affected transit or cloud regions is exposed.
Operational Impact on Hosting, VPS, and WordPress Workloads
A network outage event in the ThousandEyes report does not always mean a server went dark. Many incidents are partial—specific nodes in Chicago, Atlanta, or Seattle exhibit packet loss or withdrawn routes while others stay healthy. Yet from a user perspective, a WordPress site on a VPS becomes unreachable if the upstream transit or cloud region is degraded.
Consider the August 21 Arelion (formerly Telia Carrier) outage: it lasted one hour 21 minutes over a three-hour ten-minute window, starting at nodes in Chicago and expanding to Atlanta, Seattle, Dallas, San Jose, Sweden, and the U.K. The report states it impacted customers and downstream partners across more than 30 regions. If your hosting provider peers primarily with Arelion, or if your CDN relies on that path, visitors in those regions saw timeouts. Similarly, the Microsoft West US incident on July 23 was caused by a routine maintenance bug that removed IP routes between the datacenter and WAN; services relying on that region took roughly an hour to recover after rollback.
Cloudflare’s February 20 disruption is especially relevant for site owners using Bring Your Own IP (BYOIP). An automated internal task withdrew customer IP advertisements, causing connection timeouts for end users. The fix required halting the task and re-advertising routes globally—a 1-hour 40-minute gap. None of these were “server crashed” events; they were network control-plane failures. That distinction should shape how hosting buyers evaluate provider redundancy, not just hardware specs.

Notable 2026 Outages: Transit Carriers, Cloud, and a Hosting Provider
The weekly roundups highlight repeated offenders and diverse geographies. Arelion appears multiple times: Aug 21, Aug 14, July 2, June 2, May 19, March 20, and others. Cogent Communications shows frequent short bursts—Aug 6 (32 minutes), June 27 (9 minutes), May 25 (15 minutes), and Dec 31 (9 minutes). Zayo Group, a U.S. Tier 1 carrier, logged outages on Aug 5, July 13, May 7, April 15, March 23, and more. Cox Communications and Charter (Spectrum) also appear as ISP-side disruptions.
Cloud and edge providers are not immune. Microsoft’s West US route withdrawal was explicitly attributed to human-initiated maintenance error. Cloudflare’s BYOIP withdrawal came from an automated maintenance task bug. Google Gemini on June 10 experienced a seven-hour backend degradation with no network-layer symptom—proving ThousandEyes’ point that “if the network seems healthy but users are experiencing issues, the problem might be in the backend.”
Hosting-specific data is slimmer but present. Madgenius, a U.S.-based hosting and infrastructure service provider headquartered in Apple Valley, MN, suffered outages on Jan 16 (1h16m) and Feb 13 (1h11m), both centered on nodes in Columbus, OH. The report does not state root cause for Madgenius, and we will not speculate. The takeaway is that even specialized hosting firms sit on the same fragile transit fabric.
Resilience Lessons from Uptime Institute and ThousandEyes
Uptime Institute’s 2026 Annual Outage Analysis, referenced in the research, found that data center outages are becoming less frequent overall, but resiliency gains are slowing due to AI workloads, aging power infrastructure, and external dependencies. Critically, network and connectivity issues are the most frequently reported cause of IT service-related outages. Their survey shows 92% of operators said human error was at least a minor contributor to significant outages over three years, and half of operators reported an impactful outage in that window.
ThousandEyes’ 2025 retrospective (carried into 2026 guidance) adds that staggered five-minute configuration cycles can create intermittent global instability rather than a clean lights-off event. Missing DNS records can make healthy servers unreachable. The combination of distributed edge, third-party transit, and backend dependencies means single-symptom monitoring misses root causes.
For hosting buyers, the lesson is to treat network diversity as a feature comparable to CPU or RAM. A VPS with one upstream carrier is a single point of failure. A WordPress host without secondary DNS or multi-region failover is vulnerable to Cloudflare-style IP withdrawals. Human error during maintenance—as seen at Microsoft and Cloudflare—argues for providers with documented change-management and fast rollback.

Practical checklist / key takeaways
- Audit your hosting provider’s upstream carriers; favor multi-homed BGP over single-transit plans.
- Deploy external synthetic monitoring from multiple geographies to detect intermittent latency, not just hard downtime.
- Use redundant DNS and a secondary CDN; verify zone files after every provider change.
- Spread production workloads across at least two cloud regions or providers where latency allows.
- Review SLA credit terms and real support response times before renewing hosting contracts.
- Test backup restoration and migration paths quarterly, not only after an incident.
- Subscribe to status pages of critical transit and cloud providers, not just your host.
Conclusion
The 2026 ThousandEyes outage reports show an internet that is busy but not collapsing: hundreds of weekly events, most brief, yet increasingly centered on public cloud and Tier 1 transit. For HostXMe readers running websites, VPS instances, or managed WordPress, the risk is operational, not hypothetical. A carrier’s 20-minute node failure can erase conversions and break API integrations. By pairing the outage data with Uptime Institute’s resiliency findings, buyers can prioritize providers that publish clear postmortems, diversify network paths, and offer verifiable recovery processes. Monitoring and redundancy are no longer optional line items—they are the core of hosting health in 2026.
