IMMEDIATE ATTENTION REQUIRED: PayPal service upgrades.
PayPal is upgrading the SSL certificate used for www.paypal.com to SHA-256. This endpoint is also used by merchants using their Instant Payment Notification (IPN) product.
We can confirm that all of our shared and reseller hosting servers are SHA-256 compliant.
If your website uses an SSL certificate, then you need to make sure that the SSL uses SHA-2 and not the older SHA-1 hash algorithm. You can do that by entering your site address here.
All new certificates that we issue for hashed using SHA-2, however if you are using a SHA-1 certificate bought from us in the past, you can contact us to have it re-issued free of charge via the help desk in our client portal at https://my.kualo.com/.
