To resurrect an older thread, has anyone had success confirming a short haul hold booking?

For the second time in 3 months, I've made such a booking but every attempt to confirm it ends up with a spinning wheel of death on the website. (Or to be strictly accurate, line)

Multiple browsers and devices tried.

With the Gold line seemingly being able to answer in reasonable time again, I can confirm via that, just wondering if the IT failure is device related or BA.
