Website Keeps Going Down? Causes, Diagnosis and Permanent Fixes

A site that randomly goes down trains customers to stop coming and search engines to crawl less. The frustrating part is that intermittent failures hide their cause. This is the diagnosis path we use, followed by the fixes that actually end the cycle.

First: capture the evidence

Set up free uptime monitoring with one-minute checks. The pattern is the diagnosis: outages at traffic peaks point to resources, fixed times point to scheduled jobs or backups, random short blips point to a struggling host, and total multi-hour outages point to infrastructure or attacks.

The usual suspects

• Underpowered shared hosting: your site dies whenever a neighbour or your own traffic spikes. The most common cause by far.
• Memory or process limits: heavy plugins, page builders and uncached themes exhaust limits under modest load.
• Scheduled tasks and backups running at peak hours, locking the database.
• Bot floods and small attacks: scraping or brute-force login storms that act like traffic spikes.
• Expired domain or SSL, which looks like downtime to every visitor even though the server is fine.

Permanent fixes, in order

1. Move to hosting with guaranteed resources and real monitoring. Doubling hosting spend is cheaper than one lost day of sales.
2. Add full-page caching and a CDN so traffic spikes hit cache, not your server.
3. Audit plugins: replace the heavy ones, remove the dead ones, and keep everything updated.
4. Protect login and admin paths with rate limiting and a firewall to shrug off bot storms.
5. Schedule backups and heavy jobs in dead hours, and monitor expiry dates for domain and SSL automatically.

What uptime should you expect?

Professionally managed hosting should deliver 99.9% uptime or better, which allows under 45 minutes of downtime a month. If your history is worse and your host shrugs, that is your answer.

Make downtime someone else's job

Our managed hosting includes monitoring, caching, security and humans who respond when alerts fire, so you find out about problems after they are fixed. Talk to us about migrating; we move sites with zero data loss and near-zero downtime.

Frequently asked questions

How much downtime is normal for a website?

On quality hosting, almost none: 99.9% uptime allows roughly 45 minutes per month. Regular weekly outages are not normal and always have a findable cause.

Does downtime affect my Google rankings?

Brief rare outages are forgiven. Repeated or extended downtime reduces crawling, can drop pages from the index temporarily, and the lost user signals compound the damage.

Should I fix my current hosting or just migrate?

If the host is fundamentally underpowered or unresponsive, migrate; tuning cannot fix weak infrastructure. If the host is solid, caching and plugin audits usually end the outages.
