This morning at 4.30am I found myself following an ambulance to the nearest NHS hospital around 15 miles from my home here in the UK. This was for a heart issue, including tightness in the chest. After arriving I couldn’t obtain a mobile signal anywhere and later discovered that O2 had a massive outage, which has been widely reported since then in the press.
Luckily there was NHS guest wi-fi available, so I registered and immediately had a wi-fi signal, but no internet and this carried on for a couple hours while I was trying to send emails without luck. Eventually it dawned on that it might be 188.8.131.52 that was the problem so I disconnected the app on my Android phone and immediately had internet.
I don’t know why, but for whatever reason the NHS doesn’t seem to like 184.108.40.206, so I am posting this in the hope that Cloudflare can investigate and hopefully not have others experience this in the future.
