Current state of play with HSE PCR test availability.
Not as the news is presently covering, a "not on the day" problem, but for most of the country now a 2 day to test problem. That pink slice from Galway to Limerick will most likely go red shortly. The orange region in ~1hr.
This is the worst day I've seen. Likely to just be Mayo and Donegal left with availability tomorrow by teatime.
"while the system is coping, it obviously cannot meet the demand that is being required on a same day basis."
This quote hides the scale of the problem. By 10:30 across most of the country bar connaught,the wait for a booking is ~46 hours.
In short, the system is not, as @paulreiddublin claimed, meeting even the lighter demand of 80% of people obtaining a booking within 24 hours or seeking one.
Up till today, the pattern for the daily collapse of HSE PCR test availability for two days was simple. But midday everything east of the Shannon was gone but connaught held on to availability.
