That would make sense. I checked last night and it was down again and it is still down this morning. I suspect it's being hosted on a computer that is switched off at night or after their work day! I presume that nobody has noticed before because it's rare that we need to look at the udf's to create new code.

I think it should be removed - if it's legacy as you say (although everything I used from there works) - but especially because it's not available 24/7 anymore.
