861*2^1666295-1 is prime!
Finding a prime with "666" in the exponent on Valentine's Day? Thanks Satan, I guess. ๐Ÿ˜›
With 501608 digits it should enter the Top 5000 around #4986 and drop off very quickly.

I'm putting everything I have on ports 2000 and 9000 and that is barely keeping us in the top-5000. PrimeGrid's February rally is making it tough. All primes in February on those two ports have been and will likely be place > 4980.

If anyone would like to add some cores to those ports that would be really helpful. :-)

Added 133575 : 697*2^1670657-1 (502921 digits).

My last one was on the list for about 16 hours.

Thank you for reporting that quickly! Had that been my prime I would not have gotten it reported in time.

PrimeGrid is in the "Mountain stage" of their rally, which is only on Feb. 19th UTC. They are finding a crazy number of small primes barely larger than ours so theirs are on the list not much longer than ours. We will see if we can survive it with only about 3.5 hours to go as of this posting. Hopefully they will go back to their more normal number of rally primes after today.

I have asked Dmitry if he would add some cores. He has on port 9000 so I have moved some of my machines to port 2000 to attempt to keep both ports above water. Many thanks to Dmitry and of course to you, Tim, for sticking with it! :-)

I've found 525*2^1671068-1 recently, but it is a bit too small for Top5000 list
Let's keep pushing!

Code:
ERROR: 
The following errors have been noted:
  • Prime "525*2^1671068-1" is too small (503045 digits). Need 503161 digits or more for a general prime. Add a valid comment if you forgot it.
Fix these errors and resubmit.

The above prime would have been 5001st place on the top-5000 when it first came across port 9000 and missed 5000th place by < 20 digits at the time. :-(

PrimeGrid found 29 top-5000 primes in a single day during their Mountain Stage causing us to barely miss. I've never seen anything like that. Fortunately a large majority of them entered at > 4985th place and will drop off quickly. With that stage ending at midnight UTC (~5.5 hours prior to this post) I believe we will be able to work our way back into the top-5000 over the next 1-3 days.

551*2^1671546-1 is prime
493*2^1671839-1 is prime

Too small for top-5000.

Extremely bad luck that these primes are coming out now.

The 2nd one, once again, would have been 5001st place and missed it by < 20 digits. :-(

We had dropped to nearly 100 digits below top-5000 but have nearly caught back up. Keep chugging! :-)
