[خطا]: اختلال در دریافت اطلاعات از سرور خارج از کشور

[armin-mohammadi]

شرح خطا

سلام

از تقریبا دو روز قبل، درخواست‌ها از خارج از ایران به دامنه‌های nobitex.ir و nobitex.net به صورت پراکنده و با نرخ بالا با مشکل مواجه می‌شوند.

به نظر می‌رسد دلیلی شبیه به اختلال شبکه داشته باشد که فرایند ارتباط از همان ابتدای ssl handshake با کندی و مشکل مواجه می‌شود، ارتباط با دیگر دامنه‌ها بدون مشکل اتفاق می‌افتد ولی با دامنه‌های نوبیتکس این مشکل وجود دارد

جزئیات درخواست

1. آدرس: GET /v2/orderbook/USDTIRT

با سلام این مشکل در لایه CDN ستون است. موضوع با این تیم مطرح و نتیجه اعلام خواهد شد. با توجه به این که مشکلی در صفحه وضعیت این سرویس ثبت نشده (status.sotoon.ir) ممکن است بررسی موضوع کمی زمان نیاز داشته باشد.

[ya3er]

با سلام متاسفانه این مشکل همچنان ادامه داشته و شدت اختلال بسیار شدید است به حدی که تمامی عملیات ما را متوقف کرده است. لازم بذکر است پینگ بر روی دامنه اصلی و دامنه api از خارج از کشور مناسب است ولی تمامی ریسپانس ها از طریق api دچار اختلال هستند. @amiraliakbari

[mostafa2msh]

سلام الان بیش از دو هفته است این مشکل وجود دازد چرا رسیدگی نمیکنید؟ @amiraliakbari

[armin-mohammadi]

سلام مجدد

به نظر میرسد که دوباره این مشکل به شکل متفاوتی ایجاد شده که از سرور داخل، سریعتر جواب داده می‌شود ولی از سرور خارج در مرحله tls handshake تاخیر نسبتا زیاد ایجاد می‌شود که عملیات دریافت قیمت و سفارش گذاری را با مشکل شدید مواجه کرده است

با سلام به دلیل عدم رضایت کاربران نهایی از CDN ستون، سرویس CDN به ابر آروان تغییر یافت. در صورت بروز مجدد مشکل لطفاً اطلاع بدهید.

[armin-mohammadi]

با سلام مجدد از حوالی ساعت ۹ صبح امروز مجددا این اختلالات مشاهده می‌شود

لطفا بررسی شود @amiraliakbari

[armin-mohammadi]

با سلام این مشکل از حدود ساعت ۱۸ امروز دوباره دیده شده به شکلی که API orderbook تایم‌اوت میشه
